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", ...)

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...
