Hello up there.
I'm trying to change gcc to tcc for faster develpment on slow machines,
and the first obstacle that turned out was lack of dependency generation
on tcc side.
Attached patches try to fix that.
Thanks,
Kirill
* tcc-MD:
.gitignore += tags
tcc: Explicitly require -l<lib> for libraries
Document what tcc_fileextension does
tcc -E: Let output_default be <file>.o instead of a.out
tcc: Draft suppoprt for -MD/-MF options
tcc: Refactor "compute default outfile name" into libtcc function
Add input files/libs and reloc_output switch to TCCState
tcc: Fix typo in error (it's '%s', not '%s)
chmod a-x i386-gen.c
.gitignore += *.o *.a
.cvsignore -> .gitignore
This affectes where `tcc -E -MD file.c` will place generated dependency
information -- previously, for `tcc -E` output_default was a.out, and so
deps were put into a.d .
Avoid this behaviour, by treating `tcc -E` as `tcc -c` with respect to
output_default computation.
This will not hurt anything else (preprocessor outputs to either stdout,
or to explicitely given (-o <file>) destination, so no default filename
is used here), and on the other hand `tcc -E -MD file.c` now puts
dependencies into file.d (the same behaviour as for gcc -E).
v2:
- restructured condition a bit to make it more clear
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...
