grischka f90bad0925 tests2: cleanup
- remove -norunsrc switch
  Meaning and usage (-run -norun...???) look sort of screwed.  Also
  general usefulness is unclear, so it was actually to support exactly
  one (not even very interesting) test

James Lyon 55ea6d3fc1 x86-64 ABI fixes.
abitest now passes; however test1-3 fail in init_test. All other tests
pass. I need to re-test Win32 and Linux-x86.

I've added a dummy implementation of gfunc_sret to c67-gen.c so it
should now compile, and I think it should behave as before I created
gfunc_sret.

James Lyon e31579b076 Fixed tests on Windows (including out-of-tree problems)
Modified tcctest.c so that it uses 'double' in place of 'long double'
with MinGW since this is what TCC does, and what Visual C++ does. Added
an option -norunsrc to tcc to allow argv[0] to be set independently of
the compiled source when using tcc -run, which allows tests that rely on
the value of argv[0] to work in out-of-tree builds.

Also added Makefile rules to automatically update out-of-tree build
Makefiles when in-tree Makefiles have changed.

grischka 762a43877b configure: pass CONFIG_xxxDIR/PATH options via commandline
- except for CONFIG_SYSROOT and CONFIG_TCCDIR

Strictly neccessary it is only for CONFIG_MULTIARCHDIR
because otherwise if it's in config.h it is impossible to
leave it undefined.

But it is also nicer not to use these definitions for
cross-compilers.

grischka 05108a3b0a libtcc: new LIBTCCAPI tcc_set_options(TCCState*, const char*str)
This replaces       -> use instead:
-----------------------------------
- tcc_set_linker    -> tcc_set_options(s, "-Wl,...");
- tcc_set_warning   -> tcc_set_options(s, "-W...");
- tcc_enable_debug  -> tcc_set_options(s, "-g");

parse_args is moved to libtcc.c (now tcc_parse_args).

Also some cleanups:
- reorder TCCState members
- add some comments here and there
- do not use argv's directly, make string copies
- use const char* in tcc_set_linker
- tccpe: use fd instead of fp

tested with -D MEM_DEBUG: 0 bytes left

Thomas Preud'homme 8c56b0cf90 Revert "Added what I call virtual io to tinycc this way we can make a monolitic executable or library that contains all needed to compile programs, truly tinycc portable."
This reverts commit 59e18aee0e.
tcc is being stabilized now in order to do a new release soon.
Therefore, such a change is not appropriate now.

grischka 27d38bf23f tcc.c: fix argv index for parse_args
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"

Thomas Preud'homme 16202e054f Revert "Use CString to concat linker options"
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.

Thomas Preud'homme 1c11b857fe Use CString to concat linker options
As suggested, change type of linker_arg variable to the more appropriate CString
type, since linker_arg is about dynamically grown string.

Thomas Preud'homme 2eee100c37 Fix use after free for linker_arg
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.

Thomas Preud'homme 7fb0482a46 Support linker options passed in several -Wl param
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.

grischka 74a24d77fd libtcc: minor adjustments
- 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.

grischka 5280293d6b make: create native tcc from separate objects
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.

Sergei Trofimovich 0a50e6c933 tcc.c: fix an error when you build an object file with '-pthread' key set
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.

Kirill Smelkov 0c928da96d 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/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/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 \

        /usr/lib/libc_nonshared.a \

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", ...)

Kirill Smelkov bdae4a59c3 tcc: Refactor "compute default outfile name" into libtcc function
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...
2010-06-20 21:36:47 +04:00
Kirill Smelkov a919a373da 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...
