tests/Makefile:
- print-search-dirs when 'hello' fails
- split off hello-run
win32/include/_mingw.h:
- fix for compatibility with mingw headers
(While our headers in win32 are from mingw-64 and don't have
the problem)
tiny_libmaker:
- don't use "dangerous" mktemp
I probably broke that myself earlier. In any case parse_args
needs to start with index 0 because it is is used also recursively
to expand the shebang command from scripts such as
#!/usr/local/bin/tcc -run -L/usr/X11R6/lib -lX11
which arrives at tcc as only two argv's
"tcc" "-run -L/usr/X11R6/lib -lX11"
- remove redunant else branch
- zero-terminate linker_arg
- declare cstr_xxx as PUB_FUNC
(which are functions used in tcc.c but not in the libtcc API.
Useful for a tcc(.exe) that uses the libtcc.(so/dll))
- while at it, export PUB_FUNCs from dll
This reverts commit 1c11b857fe.
On windows, libtcc.c is compiled with ONE_SOURCE and then tcc.c is
linked to it. Thus tcc.c can only use public functions which cstr_* are
not.
elements in linker_arg are used in TCCState structure and must thus not
be freed when option parsing is finished. Declare linker_arg as a global
static variable and free it after tcc_delete has been called on TCCState
structure.
This fix commit 7fb0482a46
ld support arguments to multiple-letter options being passed in two
ways:
* -opt=arg
* -opt arg
libtool generate command line of the second form. This commit add
support for the second form so that libtool works with tcc. The way it
is done is to concatenate all -Wl options into one and then pass it to
set_linker.
- use {B} to substitute tcc_lih_path (instead of \b)
- expand CONFIG_TCC_CRTPREFIX in CONFIG_TCC_LIBPATHS
which fixes duplicate CONFIG_SYSROOT.
- put default CONFIG_SYSROOT ("") into tcc.h
- remove hack from commit db6fcce78f
because $(tccdir)/include is already in sysincludes
- configure: error out for unrecognized options.
- win32/build-tcc.bat: put libtcc into base dir where it will
find lib/include automatically, and build libtcc_test example.
This cleans up the mess from commit
8f98573658
and preceeding.
- make tcc -m64 work on windows
- execvp on windows returns 0 always, replace by spawnvp
- remove bizarre support for i386-win32-tcc -m64
This was already possible using
make NOTALLINONE=1
and is now the default.
To build as previously from one big source, use
make ONE_SOURCE=1
Cross compilers are still build from one source because using
separate objects requires separate build directories one per
platform which currently is not (yet) supported by the makefile.
We could probably use gnu-makeish target variables like
$(I386_CROSS): OUTDIR=build/i386
$(X64_CROSS): OUTDIR=build/x86-64
and so on ...
Also NEED_FLOAT_TYPES for arm-gen is removed. It was about
variables that are referenced from outside (libtcc, tccgen).
We could declare them in tcc.h (as with reg_classes) or have
them twice in arm-gen.c. I chose option 2.
The problem was partially fixed by Henry in the following patch:
tcc.c: skip -lpthread when -c option specified
But that patch had one brawback: it is sensitive to argument order,
as decision is taken during commandline parsing:
$ tcc -c a.c -o a.o -pthread # 1. works fine
tcc: error: file 'a.c' not found
$ tcc -pthread -c a.c -o a.o # 2. blows
tcc: error: cannot specify libraries with -c
This patch fixes case 2.

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...
Without -Bsymbolic, a symbol/function in a *.so can be overridden
by a symbol/function in the main module.
That is the default search order, but not supported by tcc.
With -Bsymbolic, the linker tries to resolve a symbol/function in
the current module first.
The loader in tcc implements this search order.
We do not distinguish -Bsymbolic and -Bsymbolic-function
