Replace comment by a blank
...
- fix my prev commit:
put declaration above statements to stay c89 compatible
- replace commit by a blank
#define con(a, b) a/**/b
this should yield a b, not ab

We need a ' ' after subst of m in the following case
#define m(name,r) name ## r

#define m1(a,b,c) int m(a,b)c
m0(a, b, c);
m1(a, b, c);

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", ...)

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

fix "cached include" optimization

comparing the filenames as in the #include statement can be
ambiguous if including files are in different directories.
Now caches and checks the really opened filename instead.
