Subject: [PATCH 006/200] i386-gen: preserve fp control word in gen_cvt_ftoi
- Use runtime function for conversion
- Also initialize fp with tcc -run on windows
This fixes a bug where
double x = 1.0;
double y = 1.0000000000000001;
double z = x < y ? 0 : sqrt (x*x - y*y);
caused a bad sqrt because rounding precision for the x < y comparison
was different to the one used within the sqrt function.
This also fixes a bug where
printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2));
would print
100, 99

Subject: [PATCH 009/200] win32: fix libtcc support
For "tcc -run file.c", I was trying to initialize the FP control
in a function in libtcc1.a (_runmain) before calling main.
Unfortunately that turned out to cause problems with for example
libtcc_test since such usage doesn't necessarily define a 'main'
function.
So for tcc -run we're back to relying on the FP control word
that is set in the startup code of tcc.exe rsp. libtcc.dll.
This fixes part of commit 73faaea227a53e365dd75f1dba7a5071c7b5e541

Subject: [PATCH 010/200] Generate an error when a function is redefined
Use one more bit in AttributeDef to differenciate between declared
function (only its prototype is known) and defined function (its body is
also known). This allows to generate an error in cases like:
int f(){return 0;}
int f(){return 1;}

Subject: [PATCH 020/200] Fix CONFIG_TCC_SYSINCLUDEPATHS on !win32 systems
Commit 9382d6f1 ("Fix lib, include, crt and libgcc search paths",
07-09-2013) inadvertently included an initial empty entry to the
CONFIG_TCC_SYSINCLUDEPATHS variable (for non win32 targets). In
addition to an empty line in the 'tcc -vv' display, this leads
to the preprocessor attempting to read an include file from the
root of the filesystem (i.e. '/header.h').

Subject: [PATCH 023/200] Revert "Add support for thread-local storage
variables"
TLS support in tinyCC is absolutely not ready:
- segment register not select in load and store
- no relocation added for computing offset of per-thread symbol
- no support for TLS-specific relocations
- no program header added as per Drepper document about TLS
This reverts commit 1c4afd13501f07a673aed5f130166f2ee0f30927.

Subject: [PATCH 024/200] Fix allocation of struct in registers on ARM
Allocation of struct in core and/or VFP registers on ARM is made by
manipulating the value stack to create 3 distinct zones: parameters
allocated on stack, parameters of type struct allocated in core
registers and parameters of type struct allocated in VFP registers.
Parameters of primitive type can be in any zone. This commit change the
order of the zones from stack, VFP, core to stack, core, VFP (from
highest addresses to lowest ones) in order to correctly deal the
situation when structures are allocated both in core and VFP registers.

Subject: [PATCH 028/200] Correctly align and reclaim stack at function call
* Correctly align stack in case of structure split between core
registers and stack
* Correctly reclaim stack space after function call in the case where
the stack needed padding to be aligned at function call.

Subject: [PATCH 030/200] Fix register corruption at function call on ARM
Prior to this commit, params could use some registers that do not appear
in the value stack. Therefore when generating function call, one of such
register could be reused, leading to wrong parameter content. This
happens when a structure is passed via core register, as only the first
register would appear in the value stack.

Subject: [PATCH 031/200] Fix counting of VFP regs in ARM's gfunc_prolog
Fix in gfunc_prolog for ARM the counting of the highest numbered VFP
float register used for parameter passing, rounded to 2. It can be
computed from the range of VFP float register with the highest range
start and adding the number of VFP float register occupied. This ensure
that parameter of type struct that spans over more than 2 float
registers are correctly taken into account.

Subject: [PATCH 034/200] Add support for struct > 4B returned via registers
On ARM with hardfloat calling convention, structure containing 4 fields
or less of the same float type are returned via float registers. This
means that a structure can be returned in up to 4 double registers in a
structure is composed of 4 doubles. This commit adds support for return
of structures in several registers.

Subject: [PATCH 035/200] Fix structure passing in ARM calling convention
Fix the address on stack where a structure is copied when it is a
parameter of a function call. This address must be computed from the
stack pointer and a possible padding offset.

Subject: [PATCH 038/200] Make abitest.c have predictable result
stdarg_test in abitest.c relies on a sum of some parameters made by both
the caller and the callee to reach the same result. However, the
variables used to store the temporary result of the additions are not
initialized to 0, leading to uncertainty as to the results. This commit
add this needed initialization.

Subject: [PATCH 042/200] Fix signed integer division in ARM runtime ABI
- fix computation of absolute value (clearing the sign bit does not
since integers are encoded in 2's complement)
- test sign of integer in a more conventional way (binary and with the
high bit does not work for long long due to a bug in gtst)
- spacing in include

Subject: [PATCH 044/200] Fix "Add support for struct > 4B returned via
registers"
- avoid assumption "ret_align == register_size" which is
false for non-arm targets
- rename symbol "sret" to more descriptive "ret_nregs"
This fixes commit dcec8673f21da86ae3dcf1ca3e9498127715b795
Also:
- remove multiple definitions in win32/include/math.h

Set *palign for VT_BITFIELD and VT_ARRAY types in classify_x86_64_arg as
else you happen to have in *palign what was already there. This can
cause gfunc_call on !PE systems to consider an array as 16 bytes align
and trigger the assert if the previous argument was 16 bytes aligned.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Use comisd / fcompp for float comparison (except TOK_EQ and TOK_NE)
instead of ucomisd / fucompp to detect NaN comparison.
Thanks Vincent Lefèvre for the bug report and for also giving the
solution.

Subject: [PATCH 047/200] Use libtcc.a for static link even with USE_LIBGCC
When statically linking, runtime library should be static as well. tcc
could link with libgcc.a but it's in a gcc version specific directory.
Another solution, followed by this patch, is to use libtcc.a when
statically linking, even if USE_LIBGCC was configured.

Subject: [PATCH 052/200] Move logic for if (int value) to tccgen.c
Move the logic to do a test of an integer value (ex if (0)) out of
arch-specific code to tccgen.c to avoid code duplication. This also
fixes test of long long value which was only testing the bottom half of
such values on 32 bits architectures.

Subject: [PATCH 056/200] Fix struct ret in variadic fct with ARM hardfloat
The procedure calling standard for ARM architecture mandate the use of
the base standard for variadic function. Therefore, hgen float aggregate
must be returned via stack when greater than 4 bytes and via core
registers else in case of variadic function.
This patch improve gfunc_sret() to take into account whether the
function is variadic or not and make use of gfunc_sret() return value to
determine whether to pass a structure via stack in gfunc_prolog(). It
also take advantage of knowing if a function is variadic or not move
float result value from VFP register to core register in gfunc_epilog().

Subject: [PATCH 057/200] i386: use __fixdfdi instead of __tcc_cvt_ftol
Variants __fixsfdi/__fixxfdi are not needed for now because
the value is converted to double always.
Also:
- remove __tcc_fpinit for unix as it seems redundant by the
__setfpucw call in the startup code
- avoid reference to s->runtime_main in cross compilers
- configure: fix --with-libgcc help
- tcctok.h: cleanup

Subject: [PATCH 059/200] misc. fixes
- tccgen: error out for cast to void, as in
void foo(void) { return 1; }
This avoids an assertion failure in x86_64-gen.c, also.
also fix tests2/03_struct.c accordingly
- Error: "memory full" - be more specific
- Makefiles: remove circular dependencies, lookup tcctest.c from VPATH
- tcc.h: cleanup lib, include, crt and libgcc search paths"
avoid duplication or trailing slashes with no CONFIG_MULTIARCHDIR
(as from 9382d6f1a0e2d0104a82ed805207d9e742c6b068)
- tcc.h: remove ";{B}" from PE search path
in ce5e12c2f950052d8109b6b7a56d900547705c08 James Lyon wrote:
"... I'm not sure this is the right way to fix this problem."
And the answer is: No, please. (copying libtcc1.a for tests instead)
- win32/build_tcc.bat: do not move away a versioned file

Subject: [PATCH 060/200] be stricter with aliasing
Refactoring (no logical changes):
- use memcpy in tccgen.c:ieee_finite(double d)
- use union to store attribute flags in Sym
Makefile: "CFLAGS+=-fno-strict-aliasing" basically not necessary
anymore but I left it for now because gcc sometimes behaves
unexpectedly without.
Also:
- configure: back to mode 100755
- tcc.h: remove unused variables tdata/tbss_section
- x86_64-gen.c: adjust gfunc_sret for prototype

Subject: [PATCH 075/200] Fix Fixes for PE x86_64 for fail in code
Applying 64bit relocs assumes that the CVal is initialized to zero
for the whole 64bit. Consolidate this a bit, at the same time
zeroing the .ull member more consistently when needed. Fixes segfault
on x86_64-linux using global vars in tcctest.c.

x86-64: as said when x86-64 support was added, "for long double, we use x87
FPU". And indeed, tests show that Intel's extended precision is used, not
double precision.

Subject: [PATCH 081/200] tccrun: Mark argv area as valid for bcheck
On my x86_64 box in i386 mode with address space randomization turned off,
I've observed the following:
tests$ ../tcc -B.. -b -run boundtest.c 1
Runtime error: dereferencing invalid pointer
boundtest.c:222: at 0x808da73 main()
With diagnostic patch (like in efd9d92b "lib/bcheck: Don't assume heap
goes right after bss") and bcheck traces for __bound_new_region,
__bound_ptr_indir, etc... here is how the program run looks like:
>>> TCC
etext: 0x8067ed8
edata: 0x807321d
end: 0x807d95c
brk: 0x807e000

E: __bound_ptr_indir4(0xffffd184, 0x4)
Runtime error: dereferencing invalid pointer
boundtest.c:222: at 0x808ea83 main()
So we are accessing something on stack, above stack entry for compiled
main. Investigating with gdb shows that this is argv:
tests$ gdb ../tcc
Reading symbols from /home/kirr/src/tools/tinycc/tcc...done.
(gdb) set args -B.. -b -run boundtest.c 1

132 ret = (*prog_main)(argc, argv);
132 ret = (*prog_main)(argc, argv);
(gdb) p argv
$1 = (char **) 0xffffd144
So before running compiled program, mark argv as valid region and we are
done - now the test passes.
P.S. maybe it would be better to just mark the whole vector kernel passes to
program (argv, env, auxv, etc...) as valid all at once...

Subject: [PATCH 083/200] tcctest: add back testXb (self compile with -b)
- Thanks to Kirill "tcc -b itself" should work now
(was removed in d5f4df09ff4a84dda5b03525285f03be7723376b)
Also:
- tests/Makefile:
- fix spurious --I from 767410b8750b45d63805b45ca1a2cf34d7cb4923
- lookup boundtest.c via VPATH (for out-of-tree build)
- test[123]b?: fail on diff error
- Windows: test3 now works (from e31579b0769e1f9c0947d12e83316d1149307b1a)
- abitest: a libtcc.a made by gcc is not usable for tcc
on WIndows - using source instead (libtcc.c)
- tccpe:
- avoid gcc warning (x86_64)

Subject: [PATCH 085/200] Move result of itof double conv back to VFP reg
EABI functions to convert an int to a double register take the integer
value in core registers and also give the result in core registers.
It is thus necessary to move the result back to VFP register after the
function call. This only affected integer to double conversion because
integer to float conversion used a VFP instruction to do the conversion
and this obviously left the result in VFP register. Note that the
behavior is left untouched for !EABI as the correct behavior in this
case is unknown to the author of this patch.

Subject: [PATCH 096/200] Switch float abi to softfp for int <--> float conv
This improves commit 5cbe03b9c47e676e045b4978c384087433bd6042 by
avoiding a double transfer when the default float ABI is already softfp.
It's also more clean by expliciting that the ABI is simply changed for
runtime ABI functions.

Subject: [PATCH 101/200] Fix and extend *FCAST test in tcctest.c
Result of float to unsigned integer conversion is undefined if float is
negative. This commit take the absolute value of the float before doing
the conversion to unsigned integer and add more float to integer
conversion test.

Subject: [PATCH 108/200] Def signedness != signed != unsigned for char
When checking for exact compatibility between types (such as in
__builtin_types_compatible_p) consider the case of default signedness to
be incompatible with both of the explicit signedness for char. That is,
char is incompatible with signed char *and* unsigned char, no matter
what the default signedness for char is.

Call fill_got_entry unconditionally from fill_got so as to avoid
warnings on !x86-64 architectures. This can be done since this code path
is only followed by x86-64 architecture anyway.

When bound check is enabled, tcc tries to relocate a call to
__bound_init in _init. This means that relocation (in tcc_add_bcheck)
must be done after libtcc1.a (which countains __bound_init) is loaded
but before crtn.o is loaded as this finalize _init.

Some symbol (such as __gmon_start__ but this one does not matter to tcc)
can have both a R_386_GOT32 and R_386_PLT32 relocation. It is thus not
enough to test if a GOT reloc was already done when deciding whether to
return early from put_got_entry.

Subject: [PATCH 134/200] After several days searching why my code refactoring
to remove globals was crashing, I found the problem it was because CValue
stack variables have rubish as it inital values and assigning to a member
that is smaller than the big union item and trying to recover it later as a
different member gives bak garbage.
ST_FUNC void vset(TCCState* tcc_state, CType *type, int r, int v)
{
CValue cval;
memset(&cval, 0, sizeof(CValue));
cval.i = v; //,<<<<<<<<<<< here is the main bug that mix with garbage
vsetc(tcc_state, type, r, &cval);
}
/* store a value or an expression directly in global data or in local array */
static void init_putv(TCCState* tcc_state, CType *type, Section *sec, unsigned long c,
int v, int expr_type)
{
...
case VT_PTR:
if (tcc_state->tccgen_vtop->r & VT_SYM) {
greloc(tcc_state, sec, tcc_state->tccgen_vtop->sym, c, R_DATA_PTR);
}
//<<< on the next line is where we try to get the assigned value to cvalue.i as cvalue.ull
*(addr_t *)ptr |= (tcc_state->tccgen_vtop->c.ull & bit_mask) << bit_pos;
break;
Also this patch makes vla tests pass on linux 32 bits

Subject: [PATCH 151/200] x86-64: shared libs improvement
This correctly resolves local references to global functions from
shared libs to their PLT slot (instead of directly to the target
symbol), so that interposition works.
This is still not 100% conforming (executables don't export symbols
that are also defined in linked shared libs, as they must), but
normal shared lib situations work.

This makes it so that the first PT_LOAD segment covers
ELF and program header and .interp (contained in the same page anyway,
right before the start of the first loaded section). binutils
strip creates invalid output otherwise (which strictly is a binutils
bug, but let's be nice anyway).

Subject: [PATCH 159/200] tccgen: x86_64: fix garbage in the SValue upper bits
This was going wrong (case TOK_LAND in unary: computed labels)
- vset(&s->type, VT_CONST | VT_SYM, 0);
- vtop->sym = s;
This does the right thing and is shorter:
+ vpushsym(&s->type, s);
Test case was:
int main(int argc, char **argv)
{
int x;
static void *label_return = &&lbl_return;
printf("label_return = %p\n", label_return);
goto *label_return; //<<<<< here segfault on linux X86_64 without the memset on vset
printf("unreachable\n");
lbl_return:
return 0;
}
Also::
- Rename "void* CValue.ptr" to more usable "addr_t ptr_offset"
and start to use it in obvious cases.
- use __attribute__ ((noreturn)) only with gnu compiler
- Revert CValue memsets ("After several days searching ...")
commit 4bc83ac3933efa565ae3326b55fcd711b63c073d
Doesn't mean that the vsetX/vpush thingy isn't brittle and
there still might be bugs as to differences in how the CValue
union was set and is then interpreted later on.
However the big memset hammer was just too slow (-3% overall).

Subject: [PATCH 163/200] arm: Provide alloca()
This provides a simple implementation of alloca for ARM (and enables
the associated testcase). As tcc for ARM doesn't contain an assembler,
we'll have to resort using gcc for compiling it.

Subject: [PATCH 164/200] x86_64: Create proper PLT and GOT also for -run
This makes us use the normal PLT/GOT codepaths also for -run,
which formerly used an on-the-side blob for the jump tables.
For x86_64 only for now, arm coming up.

Subject: [PATCH 165/200] arm: Use proper PLT/GOT for -run.
Same as with x86_64, disable the runtime_plt_and_got hack
for -run on arm as well. For that we need to handle several
relocations as (potentially) generating PLT slots as well.
Tested with mpfr-3.1.2 and gawk (both using --disable-shared),
there are two resp. five pre-existing problems, so no regressions.
This also works toward enabling real shared libs for arm,
but it's not there yet.

Subject: [PATCH 167/200] win32: warn people about using undeclared WINAPI
functions
*** UNCONDITIONALLY ***
Esp. sihce tinycc winapi headers are not as complete as people might
expect this can otherwise lead to obscure problems that are difficult
to debug.
(Originally 'warn_implicit_function_declaration' was set to 1
always for windows but someone must have deleted that line)

Subject: [PATCH 184/200] build: add initial NetBSD support.
Not able to generate ELF files on NetBSD yet (lacks the note and crt1.o
is actually named crt0.o on NetBSD), but -run works with these extra
defines:
-D__lint__ -D"__symbolrename(x)=asm(#x)" -D__NetBSD__
The -D__lint__ is an ugly hack, TCC should be able to emulate GCC just
fine, but it seems TCC doesn't support __builtin_va_list yet?
typedef __builtin_va_list __va_list;
/usr/include/sys/ansi.h:72: error: ';' expected (got "__va_list")

Subject: [PATCH 190/200] Parse and emit hidden visibility
This adds parsing of (GCC compatible) visibility attribute
in order to mark selected global symbols as hidden. The generated
.o files contain hidden symbols already, the TCC linker doesn't
yet do the right thing.
