Also:
- regenerate all tests/pp/*.expect with gcc
- test "insert one space" feature
- test "0x1E-1" in asm mode case
- PARSE_FLAG_SPACES: ignore \f\v\r better
- tcc.h: move some things
Makefile :
- do not 'uninstall' peoples /usr/local/doc entirely
libtcc.c :
- MEM_DEBUG : IDE-friendly output "file:line: ..."
- always ELF for objects
tccgen.c :
- fix memory leak in new switch code
- move static 'in_sizeof' out of function
profiling :
- define 'static' to empty
resolve_sym() :
- replace by dlsym()
win32/64: fix R_XXX_RELATIVE fixme
- was fixed for i386 already in
8e4d64be2f
- do not -Lsystemdir if compiling to .o
tccgen.c:gv() when loading long long from lvalue, before
was saving all registers which caused problems in the arm
function call register parameter preparation, as with
void foo(long long y, int x);
int main(void)
{
unsigned int *xx[1], x;
unsigned long long *yy[1], y;
foo(**yy, **xx);
return 0;
}
Now only the modified register is saved if necessary,
as in this case where it is used to store the result
of the post-inc:
long long *p, v, **pp;
v = 1;
p = &v;
p[0]++;
printf("another long long spill test : %lld\n", *p);
i386-gen.c :
- found a similar problem with TOK_UMULL caused by the
vstack juggle in tccgen:gen_opl()
(bug seen only when using EBX as 4th register)
Except
- that libtcc1.a is now installed in subdirs i386/ etc.
- the support for arm and arm64
- some of the "Darwin" fixes
- tests are mosly unchanged
Also
- removed the "legacy links for cross compilers" (was total mess)
- removed "out-of-tree" build support (was broken anyway)

- "utf8 in identifiers"
from 936819a1b9
- CValue: remove member str.data_allocated
- make tiny allocator private to tccpp

- define_push: take int* str again
Also:
- allow more than one item per line
- respect "quoted items" and escaped quotes \"
(also for LIBTCCAPI tcc_setoptions)
- cleanup some copy & paste
after several "fixes" and "improvements"

feature did not work at all
- Use 'once' flag, not 'ifndef_macro'
- Ignore filename letter case on _WIN32
- Increment global pp_once for each compilation
- would parse linker args in two different places
- would mess up "tcc -v ..." output:
tcc -v test.c
-> test.c
+> test.c
- would use function "tcc_load_alacarte()" to do the contrary of
what its name suggests.
This reverts commit 19a169ceb8.
A patch is implemented as suggested in tinycc-devel mail list.

Subject: [PATCH] Add --{no,}-whole-archive support
I resurrected the patch supplied to the mailing list in 2009
Since --whole-archive is a useful flag to get tcc working with
autotools, and of course in its own right, I suggest you have a look
at the patch and see if it is acceptable. I cannot see any suggestion
that it was actively rejected last time round, just no evidence that
it was ever added.
Fix it to actually be able to parse 64bit immediates (enlarge
operand value type). Then, generally there's no need for accepting
IM64 anywhere, except in the 0xba+r mov opcodes, so OP_IM is
unnecessary, as is OPT_IMNO64. Improve the generated code a bit
by preferring the 0xc7 opcode for im32->reg64, instead of the
im64->reg64 form (which we therefore hardcode).
... for fast redeclaration checks
Also, check function parameters too:
void foo(int a) { int a; ... }
Also, try to fix struct/union/enum's on different scopes:
{ struct xxx { int x; };
{ struct xxx { int y; }; ... }}
and some (probably not all) combination with incomplete
declarations "struct xxx;"
Replaces 2bfedb1867

don't catch redefinition for local vars. With this option on
tcc accepts the following code:
int main()
{
int a = 0;
long a = 0;
}
But if you shure there is no problem with your local variables,
then a compilation speed can be improved if you have a lots of
the local variables (50000+)
- uses new `TinyAlloc`-ators for small `TokenSym`, `CString` and
`TokenString` instances
- conditional `TAL_DEBUG` for mem leaks and double frees detection
- on `TAL_DEBUG` collects allocation origin (file + line)
- conditional `TAL_INFO` for allocators stats (in release mode too)
- chain a new allocator twice current capacity on buffer exhaustion
A problem was in TOK_ASMDIR_text:
- sprintf(sname, ".%s", get_tok_str(tok1, NULL));
+ sprintf(sname, "%s", get_tok_str(tok1, NULL));
When tok1 is '.text', then sname is '..text'

Subject: Allow tcc arguments to be read from @listfiles
This allows all @ prefixed arguments to be treated as listfiles
containing list of source files or tcc options where each one is on a
separate line. Can be used to benchmark compilation speed with
non-trivial amount of source files.
The impl of `tcc_parse_args` had to be moved to a new function that is
able to be called recursively w/ the original one remaining as a driver
of the new one. Listfiles parsing happens in a new
`args_parser_add_listfile` function that uses `tcc_open`/`tcc_close/inp`
for buffered file input.

Subject: Add VS2015 solution and project files to `win32/vs2015`
directory
This allows release/debug builds for both x86 and x64 targets. Some
warnings had to be suppressed.
Output libtcc.dll and tcc.exe are copied to parent `win32` directory
w/ a post-build action.
When tccboot kernels compiles with
'Identifiers can start and/or', this kernel don't start.
It is hard to find what is wrong.
PS: there was no test for identifiers in *.S with '.'
There was already support for -dD option but in contrast -dM dumps only `#define` directives w/o actual preprocessor output.
The original -dD output differs from gcc output by additional comment in front of `#define`s so this quirk is left for -dM as well.
modified version of the old one which don't allow '.'
in #define Identifiers. This allow correctly preprocess
the following code in *.S
#define SRC(y...) \
9999: y; \
.section __ex_table, "a"; \
.long 9999b, 6001f ; \
// .previous
SRC(1: movw (%esi), %bx)
6001:
A test included.
remove non-existent or duplicate directories from include paths
if -fnormalize-inc-dirs is specified. This will help
to compile current coreutils package
- Identifiers can start and/or contain '.' in PARSE_FLAG_ASM_FILE
- Move all GAS directives under TOK_ASMDIR prefix
This patches breaks compilation of the tccboot (linux 2.4.26
kernel). A test.S which fails with this patches:
#define SRC(y...) \
9999: y; \
.section __ex_table, "a"; \
.long 9999b, 6001f<---->; \
.previous
SRC(1:<>movw (%esi), %bx<------>)
// 029-test.S:7: error: macro 'SRC' used with too many args
A CString used to be copied into a token string, which is an int array.
On a 64-bit architecture the pointers were misaligned, so ASan gave
lots of warnings. On a 64-bit architecture that required memory
accesses to be correctly aligned it would not work at all.
The CString is now included in CValue instead.
tcc_normalize_inc_dirs: normally no problem to be absolutly
gcc compatible as long as it can be done the tiny way.
This reverts to the state before recent related commits and
reimplements a (small) part of it to fix the reported problem.
Also: Revert "parsing "..." sequence"
c3975cf27c
&& p[1] == '.'
is not a reliable way to lookahead
- avoid memory allocation by using its (int) token number
- avoid additional function parameter by using Attribute
Also: fix some strange looking error messages
