Add support for __REDIRECT_NTH as eglibc makes use of this macro to
redirect long double functions to long functions on arch not supporting
long double.
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.
- Fix a wrong calculation for size of struct
- Handle cases where struct size isn't multple of 8
- Recover vstack after memcpy for pushing struct
- Add a float parameter for struct_assign_test1 to check SSE alignment
This reverts commit 433ecdfc9d.
The patch breaks e.g. with
for ((i = 10); --i;);
In particular to check for a type decl. this is not sufficient:
if (tok < TOK_UIDENT) {
A future approach to c99 loop variables might instead use:
if (parse_btype(...)) {
plus refactor function decl() accordingly.
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
Since for upcoming -MD support default _compile_ output file be needed
even when preprocesssing (tcc -E), let's move this code out of one
particular condition block into a common function, so that we could use
it in deps generation code too.
v2:
- As suggested by grischka, moved into libtcc function instead of always
computing near start of main()
- There is a FIXME about how to return result - I don't want to bother
callers with allocating temp buffers, not I think it will be a good
idea to hook default_target to TCCState. Clearly, I'm to used to
things like std::string and python's str...
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...
We no longer use CVS, so let's teach Git about what files to ignore...
... though doing `git status` after make + `make test` still gives
untracked content:
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# alloca86-bt.o
# alloca86.o
# bcheck.o
# libtcc.a
# libtcc.o
# libtcc1.a
# libtcc1.o
# tcc.o
See next patch about this stuff.
configure and gcctestsuite.sh shell scripts contains bashisms although being
bourne shell script. This patch fixes the following bashisms:
* Use of $RANDOM variable (replaced by reading in /dev/urandom)
* Use == in tests instead of just =
* Use $[] for arithmetic computation istead of $(())
