9b09fc376e Add support of asm label for functions. 
Add support for asm labels for functions, that is the ability to rename
a function at assembly level with __asm__ ("newname") appended in
function declaration.

0c928da96d tcc: Draft suppoprt for -MD/-MF options 
In build systems, this is used to automatically collect target
dependencies, e.g.

    ---- 8< (hello.c) ----
    #include "hello.h"
    #include <stdio.h>

    int main()
    {
        printf("Hello World!\n");
        return 0;
    }

$ tcc -MD -c hello.c    # -> hello.o, hello.d
$ cat hello.d
hello.o : \
        hello.c \
        hello.h \
        /usr/include/stdio.h \
        /usr/include/features.h \
        /usr/include/bits/predefs.h \
        /usr/include/sys/cdefs.h \
        /usr/include/bits/wordsize.h \
        /usr/include/gnu/stubs.h \
        /usr/include/bits/wordsize.h \
        /usr/include/gnu/stubs-32.h \
        /home/kirr/local/tcc/lib/tcc/include/stddef.h \
        /usr/include/bits/types.h \
        /usr/include/bits/wordsize.h \
        /usr/include/bits/typesizes.h \
        /usr/include/libio.h \
        /usr/include/_G_config.h \
        /usr/include/wchar.h \
        /home/kirr/local/tcc/lib/tcc/include/stdarg.h \
        /usr/include/bits/stdio_lim.h \
        /usr/include/bits/sys_errlist.h \

NOTE: gcc supports -MD only for .c -> .o, but in tcc, we generate
dependencies for whatever action is being taken. E.g. for .c -> exe, the
result will be:

$ tcc -MD -o hello hello.c  # -> hello, hello.d
hello: \
        /usr/lib/crt1.o \
        /usr/lib/crti.o \
        hello.c \
        hello.h \
        /usr/include/stdio.h \
        /usr/include/features.h \
        /usr/include/bits/predefs.h \
        /usr/include/sys/cdefs.h \
        /usr/include/bits/wordsize.h \
        /usr/include/gnu/stubs.h \
        /usr/include/bits/wordsize.h \
        /usr/include/gnu/stubs-32.h \
        /home/kirr/local/tcc/lib/tcc/include/stddef.h \
        /usr/include/bits/types.h \
        /usr/include/bits/wordsize.h \
        /usr/include/bits/typesizes.h \
        /usr/include/libio.h \
        /usr/include/_G_config.h \
        /usr/include/wchar.h \
        /home/kirr/local/tcc/lib/tcc/include/stdarg.h \
        /usr/include/bits/stdio_lim.h \
        /usr/include/bits/sys_errlist.h \
        /usr/lib/libc.so \
        /lib/libc.so.6 \
        /usr/lib/ld-linux.so.2 \
        /lib/ld-linux.so.2 \
        /usr/lib/libc_nonshared.a \
        /lib/libc.so.6 \
        /usr/lib/libc_nonshared.a \
        /home/kirr/local/tcc/lib/tcc/libtcc1.a \
        /usr/lib/crtn.o \

So tcc dependency generator is a bit more clever than one used in gcc :)

Also, I've updated TODO and Changelog (in not-yet-released section).

v2:

(Taking inputs from grischka and me myself)

- put code to generate deps file into a function.
- used tcc_fileextension() instead of open-coding
- generate deps only when compilation/preprocessing was successful

v3:

- use pstrcpy instead of snprintf(buf, sizeof(buf), "%s", ...)

a919a373da Add input files/libs and reloc_output switch to TCCState 
files[0], and reloc_outpu will be needed for (upcoming in the next
patch) "compute default outfile name" refactored into libtcc function.

Also, since for symmetry and from libification point of view, it makes
some sense to also put all information about what was given as input to
compilation into TCCState, let's not only put files[0], but all
files and all libraries given explicitely by user.

One point: I've used bitfield for reloc_output & trimmed down
output_type to 8 bits so that TCCState stays the same in size, and also
access to output_type is (hopefully) is not slower.

By the way -- as of today, sizeof(TCCState) on i686-pc-linux-gnu is 2884
bytes...

3ad3168125 Clean changes introduced by 47abdbd 
* Replace the save/load_buffer_state by a dynarray approach:
  - Filename and libname are added to a dynarray when first encountered
  - Load repeatedly the files in the dynarray until no new undefined
    symbol are encountered
* Replace snprintf by sprintf in libname_to_filename
* Use tcc_fileextension in filename_to_libname
* Introduce a tcc_strcpy_part fonction to copy only a subset of a
  string
* Move new_undef_syms declaration from tcc.h to tccelf.c

2650584ac4 Recognize -Wl,-Bsymbolic 
Without -Bsymbolic, a symbol/function in a *.so can be overridden
by a symbol/function in the main module.
That is the default search order, but not supported by tcc.

With -Bsymbolic, the linker tries to resolve a symbol/function in
the current module first.
The loader in tcc implements this search order.

We do not distinguish -Bsymbolic and -Bsymbolic-function

50b040ef83 win64: add tiny unwind data for setjmp/longjmp 
This enables native unwind semantics with longjmp on
win64 by putting an entry into the .pdata section for

Also, the function now use a fixed stack and store arguments
into X(%rsp) rather than using push.
