- generate and use SYM@PLT for plt addresses
- get rid of patch_dynsym_undef hack (no idea what it did on FreeBSD)
- use sym_attrs instead of symtab_to_dynsym
- special case for function pointers into .so on i386
- libtcc_test: test tcc_add_symbol with data object
- move target specicic code to *-link.c files
- add R_XXX_RELATIVE (needed for PE)
add_elf_sym is a confusing name because it is not clear what the
function does compared to put_elf_sym. As a matter of fact, put_elf_sym
also adds a symbol in a symbol table. Besides, "add_elf_sym" fails to
convey that the function can be used to update a symbol (for instance
its value). "set_elf_sym" seems like a more appropriate name: it will
set a symbol to a given set of properties (value, size, etc.) and create
a new one if non exist for that name as one would expect.
- call RtlDeleteFunctionTable
(important for multiple compilations)
- the RUNTIME_FUNCTION* is now at the beginning of the
runtime memory. Therefor when tcc_relocate is called
with user memory, this should be done manually before
it is free'd:
RtlDeleteFunctionTable(*(void**)user_mem);
[ free(user_mem); ]
- x86_64-gen.c: expand char/short return values to int
FreeBSDs system headers contain unconditional usage of
macros like __aligned(x), which are only conditionally defined
in sys/cdefs.h (conditional on __GNUC__ or __INTEL_COMPILER).
Bug in FreeBSD, but as work-around we can define __GNUC__ which
picks up these defs.
[This also moves back the glibc defines we had before into the
non-BSD ifdef branch]
__GNUC__ nowadays as macro seems to mean the "GNU C dialect"
rather than the compiler itself. See also
http://gcc.gnu.org/ml/gcc/2008-07/msg00026.html
This patch will probably cause problems of various kinds but
maybe we should try nonetheless.
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
#ifndef guards are cached, however after #elif on the
same level, the file must be re-read.
Also: preprocess asm as such even when there is no
assembler (arm).
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)
-- Not a fix
This reverts commit 089ce6235c.
Revert "handle a -s option by executing sstrip/strip program"
-- related, not a fix.
This reverts commit 5cd4393a54.
- "utf8 in identifiers"
from 936819a1b9
- CValue: remove member str.data_allocated
- make tiny allocator private to tccpp
- allocate macro_stack objects on heap
because otherwise it could crash after error/setjmp
in preprocess_delete():end_macro()
- mov "TinyAlloc" defs to tccpp.c
- 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
- 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.
... 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
and 07d896c8e5
Fixes cf95ac399c
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+)

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.
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.
remove non-existent or duplicate directories from include paths
if -fnormalize-inc-dirs is specified. This will help
to compile current coreutils package
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
