in the same pass like
tcc -E one.c two.c three.c -o combined.i
This will allow to speed up a compilation process by using a commamd like
tcc -E *.c | tcc -o program.exe -xc -
It looks that multi-times initialization don't affect anything.
Only call to the free_defines(define_start) in tcc_preprocess()
is removed in assumption that free_defines(NULL) in
tcc_cleanup() will free all defines.
With this option on a defines are included into the output
(inside comments). This will allow to debug a problems like:
In file included from math.c:8:
In file included from /usr/include/math.h:43:
/usr/include/bits/nan.h:52: warning: NAN redefined
tcc -E -P
do not output a #line directive, a gcc compatible option
tcc -E -P1
don't follow a gcc preprocessor style and do output a standard
#line directive. In such case we don't lose a location info when
we going to compile a resulting file wtith a compiler not
understanding a gnu style line info.
A cpp from gcc do this.
A test case:
tcc -E tccasm.c -o tccasm.i
tcc -E tccasm.i -o tccasm.ii
After a patch the line numbers in tccasm.ii are the same
as in tccasm.i
This adds some more support for properly transfering some
offsets over the different stages of a relocations life.
Still not at all psABI compliant and DSOs can't yet be generated.
But it runs the testsuite in qemu-arm64.
libtcc.c: Add greloca, a generalisation of greloc that takes an addend.
tcc.h: Add greloca and put_elf_reloca.
tccelf.c: Add put_elf_reloca, a generalisation of put_elf_reloc.
tccgen.c: On x86_64, use greloca instead of greloc in init_putv.
The back end functions gen_op(comparison) and gtst() might allocate
registers so case_reg should be left on the value stack while they
are called and set again afterwards.
Add a ".i" extension as alias for ".c"
GCC and file extensions:
.i C source code which should not be preprocessed.
Before a patch:
./tcc -E tccasm.c -o tccasm.i
./tcc -c tccasm.i -o tccasm.o
tccasm.i:1: error: unrecognized file type
* tccpp.c (parse_number): `shift' should be 1 while parsing binary
floating point number.
* tests/tests2/70_floating_point_literals.c: New test cases for
floating point number parsing.
Clear CFLAGS and LDFLAGS to build the tests, in case the main Makefile
passes some flags that aren't handled by tcc (we are not compiling tcc
here, we are using tcc to compile the tests).
Prevent libtcc1.a to be compiled with -fstack-protector-strong, so that
linking with tcc doesn't fail because symbol '__stack_chk_fail_local' is
not present in libtcc1.a. This is useful only if the CFLAGS passed from
the main Makefile contain this flag.
This for example suppresses string constants such as with
int main()
{
return sizeof "foo";
}
Actually, setting
nocode_wanted = 1;
in libtcc.c for the initial global level seemed wrong, since
obviously "nocode_wanted" means code as any side effects, also
such as string constants.
This reverts a part of 2de1b2d14c
