Prevent any decoration that would otherwise affect an exported
PE function. For example, given the following:
__declspec(dllexport) __stdcall
int decorated(int arg) {
return 0;
}
__declspec(dllexport) __stdcall __attribute__((nodecorate))
int undecorated(int arg) {
return 0;
}
The following exported functions can now be seen in the DLL:
_decorated@4
undecorated
The attribute is recognised for all targets but only
affects PE codegen. I'm not sure whether this would be
useful for other targets; its intended use was to allow
the creation of a DLL matching an existing set of signatures.
Forgot about it. It allows to compile several
sources (and other .o's) to one single .o file;
tcc -r -o all.o f1.c f2.c f3.S o4.o ...
Also:
- option -fold-struct-init-code removed, no effect anymore
- (tcc_)set_environment() moved to tcc.c
- win32/lib/(win)crt1 minor fix & add dependency
- debug line output for asm (tcc -c -g xxx.S) enabled
- configure/Makefiles: x86-64 -> x86_64 changes
- README: cleanup
Today by accident i had to deal with linker problems of some
software and found an issue that mentioned DT_RUNPATH, which
mentioned that DT_RPATH is legacy and searched for
$LD_LIBRARY_PATH, whereas the newer DT_RUNPATH is searched
thereafter. Completely unencrypted! Well. For what's it worth,
i for one am astonished because of course i want to override
$LD_LIBRARY_PATH, but it surely has its merites, smart people came
to the conclusion, did they.
The attached diff below seems to be sufficient to support
DT_RUNPATH instead of DT_RPATH with tcc(1). But i have no insight
in what --enable-new-dtags is supposed to change in addition, so
i wonder.
Ciao!

- 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.
* Documentation is now in "docs".
* Source code is now in "src".
* Misc. fixes here and there so that everything still works.
I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...
library Cello: http://libcello.org/ which uses `$` and several
variations of as macros.
There is also RayLanguage which also uses it as a macro for a kind of
ObjC style message passing: https://github.com/kojiba/RayLanguage
This is a patch from Daniel Holden.
- a warning: unnamed struct/union that defines no instances
- allow a nested named struct declaration w/o identifier
only when option -fms-extensions is used
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.
Should fix some warnings wrt. access out of array bounds.
tccelf.c: fix "static function unused" warning
x86_64-gen.c: fix "ctype.ref uninitialzed" warning and cleanup
tcc-win32.txt: remove obsolete limitation notes.
Implement C99 Variable Length Arrays in tinycc:
- Support VLA with multiple level (nested vla)
- Update documentation with regards to VT_VLA
- Add a testsuite in tcctest.c
