This reverts commit 2507c71704.
Why crowd up search-paths for the normal native compiler with
all sort of invalid stuff. Why -UCONFIG_TRIPLET if it isn't
set at all for cross-compilers. Also, the patch still didn't
do anything useful "out of the box".
Instead I'd suggest to do something more simple and more effective.
See Makefile:
- set search paths for cross-compilers to /usr/<triplet> by default
- Install any built "xxx-tcc" and "xxx-libtcc1.a", even if not listed
with PROGS_CROSS/LIBTCC1_CROSS
- Support ELF-<target> = ... to set the elf interpreter
Some common gnu-triplets are supported by default
TRIPLET-i386 ?= i386-linux-gnu
TRIPLET-x86_64 ?= x86_64-linux-gnu
TRIPLET-arm ?= arm-linux-gnueabihf
TRIPLET-arm64 ?= aarch64-linux-gnu
TRIPLET-riscv64 ?= riscv64-linux-gnu
Other triplets can be given explicitly, for example like this:
$ make cross-arm-eabi TRIPLET-arm-eabi=arm-linux-gnueabi
$ sudo make install
On an armeabi-v7a device (phone) in the termux app with
clang & make installed this passes all the tests.
Can be used as a cross compiler to create "native apps" as well.
Example 'config-extra.mak' for the cross arm-eabi-tcc:
SYSROOT = <path_to_android_ndk...>/sysroot/usr
TRIPLET = arm-linux-androideabi
ANDRVER = 32
ROOT-arm-eabi = $(SYSROOT)
CRT-arm-eabi = {R}/lib/$(TRIPLET)/$(ANDRVER)
LIB-arm-eabi = {B};{R}/lib/$(TRIPLET)/$(ANDRVER);{R}/lib/$(TRIPLET)
INC-arm-eabi = {B}/lib/include;{R}/include/$(TRIPLET);{R}/include
DEF-arm-eabi = -DTCC_TARGET_ARM -DTCC_ARM_VFP -DTCC_ARM_EABI
DEF-arm-eabi += -DTARGETOS_ANDROID -DCONFIG_TCC_PIE -DCONFIG_NEW_DTAGS
DEF-arm-eabi += -DCONFIG_TCC_ELFINTERP=\"/system/bin/linker\"
# on unix replace ';' by ':'.
$ ./configure && make cross-arm-eabi && make install
Allows to create dynamic executables, using the code path
for TCC_OUTPUT_DLL but add an .interp header (plus a FLAGS_1
entry in the dynamic section to make 'readelf' say "PIE")
Introduces TCC_OUTPUT_DYN as alias for TCC_OUTPUT_DLL.
There is no runtime option, only one to configure:
./configure --config-pie

... rather than from tccdir. Also allows to load cross
versions of bcheck.o etc. (if we would build them which
we currently don't).

Better avoid global variables, at least in new code.
tccdbg.c hopefully should be logically identical to the
former parts in tccgen/elf.c (s1 tccstate added in some
places)
tccelf.c: dwarf linkage seems special per dwarf rather
than special per target.
/* Use "-g" as alias for "-g1". Use "-g0" to disable debug */
So not using -g is now the alias for -g0 ?!?

Currently used only with 'tcc_compile_sem' to protect
tcc_compile(), but can be used with other semaphores
Also fix deadlock when tcc_enter_state() is called
recursively for the same state, for example with
tcc_warning() from #pragma comment(option,"...")
Also:
- libtcc.c: error1(): use cstr_[v]printf()
- tcc.h: set TCC_USING_DOUBLE_FOR_LDOUBLE for macho-arm64
(rather than for macho-X86_64)
- tcc.h: define TCC_TARGET_MACHO on __APPLE__ by default
- tcc.h: cleanup TCCState, move DEFASM token stuff to tcctok.h
- tccgen.c: more static
- Makefile/tcc.c: review githash
- tccpe/tcctools: use read() instead of fgets() in pe_load_def()
(all files opened by tcc for reading are now read via 'int fd')
- configure/win32: don't preset CONFIG_TCCDIR (to allow to override it)
- tcc.c -bench: do not include output/run-time
configure:
- re-enable apple M1-arm64
- however, with --cpu=x86_64, set -arch in CFLAGS/LDFLAGS too
(assume rosetta)
Makefile:
- re-enable osx cross-test (Please do not disable tests)
tcc.h
- set TCC_IS_NATIVE for TCC_TARGET_MACHO on __APPLE__
- apply TCC_USING_DOUBLE_FOR_LDOUBLE for x86_64-osx
libtcc.c:
- cleanup tcc_add_file_internal()
- new function char *tcc_load_text(int fd); and use it for tbd files
- remove any error messages that were just for debugging the
templates really
- don't use c99 in tcc (array designators etc.)
- remove memory model type (cannot be an own type really)
and move memory model defines from built-in to stdatomics.h
- apply normal casts to non-pointer atomic_function arguments
- tidy the library support
- add some tests for errors/warnings
Also:
- Makefile: move GIT_HASH stuff from CFLAGS to DEFINES and into
main section (away from what is included by tests for example)
- tccelf.c/tccgen.c: avoid some warnings with newer GCC
lib/tcov.c:
- can't be cross-compiled (needs stdio.h)
- can be included in libtcc1.a
Reason why bt-xxx.o/bcheck.o are linked separatly is because we
don't want then to linked into exe's and dlls at the same time.
tccgen.c: debug_modes
- don't waste debug function calls during normal execution.
libtcc.c:
- mem_debug: no C99 features in tcc please, for example
({compound expressions}): do not use.
tccgen.c: struct_layout:
- unaligned access is completely ok for most targets.
- Moreover the patch was triggering single byte mode even
for normal aligned access (as with tcc's SymAttr)
static Sym label: don't do this
arm-gen.c:
- use some #ifdefs to explain some code
tccpp.c:
- cleanup UCN chars
libtcc.c:
- replace openbsd library search
configure:
- cleanup strip fallouts
tccgen.c:
- expr_cond(): remove an exotic optimization that eventually
got fixed to do the contrary by a gv(RC_InT)
- pop_local_syms(): remove some args
- init_putv() : use write##le functions to avoid cross-compiler
unaligned access
- __bt_init(): remove unused param 'mode'
I have implemented the -ftest-coverage option. It works a bit different
from the gcc version. It output .tcov text file which looks almost the
same as a gcov file after a executable/so file is run.
Add lib/tcov.c file
Modify Makefiles to compile/install it
Add -ftest-coverage option in tcc.c/tcc.h/tcc-doc.texi
Add code to tccelf.c/tccgen.c/tccpe.c
Add gen_increment_tcov to tcc.h/*gen.c
unrelated changes:
Add sigemptyset in tccrun.c
Fix riscv64-gen.c tok_alloc label size
The small common parts within elf_output_file() aren't
worth the many #ifdefs. Also, set section sizes and
allocate section names in 2 separate functions.
moved target_machine defines to the <target>-gen.c files.
Also:
- c2str.c moved into conftest.c
- tccdefs.h ; defined(__TINYC__) && !defined(_LOCORE) removed
(in tinycc __TINYC__ is always defined and _LO... is never.)
- stddef.h : too many #ifdefs, removed
- tccgen.c:stabs: support win32 long doubles aka doubles.
- win32: math.h/tcc_libm.h: fix pointer mismatch in modfl
- tccpp.c: increment include_stack_ptr after the file was
actually found otherwise it would print
"in file included from <itself>: file not found..."
tcc_define_symbol(): now only for -D on command line
include/tccdefs.h: converted to strings and compiled into
the tcc executable. Can be disabled with
./configure --config-predefs=no
In this case include/tccdefs.h is loaded at runtime. This is
default for other build-methods (build-tcc.bat) also (to avoid
some complexity).
Also:
- lib/Makefile: fix typo
- tcc.h : avoid _strto(u)i64 (for TCC on WIN98/2K)
- tccpp.h:cstr_printf() : workaround incompatible vsnprintf's
(generally faster too)
- The compiler should not use these
- However tccrun.c & libtcc1.a files should use these
Also:
- use s1->loaded_dlls for loaded dlls instead of dlopens
- alpine musl: fully supported now and tested
- ./configure ...
--config-backtrace=no : disable backtraces
--config-bcheck=no : disable bcheck
- tests:dlltest: enable by default
- tccrun.c : simplify mmaps
- __builtin_alloca : always use asm-alias (instead of #define)
- tccpe.c : use write32le
- tccpe.c: commit "tidy support for helper function" created
STT_NOTYPE symbols and hence relied on ad-hoc detection which
didn't work for x86_64 (as reported by Christian Jullien)
- tccgen.c: However to be more safe the helper symbols are
now made STT_FUNC anyway (via new VT_ASM_FUNC).
Also:
- tcc.h: minor reorder
- riscv64-*, arm64-*, tccmacho.c: avoid some gcc format-warnings
(mingw-gcc complains about "%llx" being "unknown conversion",
although it does work since Vista or so)
- configure/Makefile : cleanup, really use CC_NAME
- tccasm.c : remove C99 construct that MSVC doesn't compile
- arm-gen.c, x86_64-gen.c, riscv64-gen.c, tccmacho.c : ditto
- arm64-gen.c: commit 383acf8eff wrote:
"Instead of a cast, it would be better to pass the exact type."
It is true that there are better solutions but it is not
passing the exact type (I think).
- tcctest.c: revert "fix cast test for clang" 03646ad46f
this obviously wants to test non-portable conversions
- 114_bound_signal.test: clock_nanosleep is too new for older
linuxes, just use sleep() instead
* instead of /usr/include use the current SDK path as system
include directory (/usr/include is empty with current tools)
(this also removes the need to add these paths in individual
Makefiles)
* define _DARWIN_C_SOURCE in tcc.h to get the full set of decls
from system headers (e.g. vsnprintf), similar to _GNU_SOURCE
(and don't define _ANSI_SOURCE in the main Makefile anymore)
* tests/tests2/Makefile: remove the -w flag, it's added when necessary
in the rules generating the .expect files
