70dbe169b2 fix a preprocessor for .S
* tell a right line number in error message
      if a #line directive is wrong

    * don't print an error message if we preprocess a .S file
      and #line directive is wrong. This is the case of
      the
        # 4026 bytes
      comment in *.S file.

    * preprocess_skip: skip a line with
	    if (parse_flags & PARSE_FLAG_ASM_COMMENTS)
       		p = parse_line_comment(p);
      if line starts with # and a preprocessor command not found.

      A test program:
      #if defined(CONFIG_EDD) || defined(CONFIG_EDD_MODULE)
	# This repeats until either a device doesn't exist, or until
      #endif

    * remove a second definition of the TOK_FLAG_* and PARSE_FLAG_*
      from the tccpp.c

7e7e6148fd fix installation amd bcheck for Windows
* define targetos=Windows when --enable-tcc32-mingw, --enable-cygwin, ...
    * use TARGETOS insteed HOST_OS when selecting PROGS
    * use "$(tccdir)" insteed $(tccdir) on install (spaces in path)
    * install tcc.exe too
    * produce bcheck.o when cross-compiling too (lib/Makefile)
    * force bcheck.o linking by compiling inside tcc_set_output_type()
      a dummy program with local array. Otherwise bcheck.o may be not linked.
    * replace %xz format specifier with %p in bcheck (don't supported on
      Windows)
    * call a __bound_init when __bound_ptr_add, __bound_ptr_indir,
      __bound_new_region, __bound_delete_region called.
      This is because a __bound_init inside ".init" section is not called
      on Windows for unknown reason.
    * print on stderr a message when an illegal pointer is returned:
        there is no segmentation violation on Windows for a program
        compiled with "tcc -b"
    * remove "C:" subdir on clean if $HOST_OS = "Linux"
    * default CFLAGS="-Wall -g -O0" insteed CFLAGS="-Wall -g -O2"
      to speed up compilation and more precise debugging.

5cd4393a54 handle a -s option by executing sstrip/strip program 2015-04-10 06:53:48 +03:00

089ce6235c output all sections if we produce an executable file
tcc w/o -g option generate an executable file which format
    is not recognized by binutils. It is like stripped one but
    binutils don't think so. Solution: generate not stripped
    file which can be correctly stripped by external utils.

    may be there is a need to handle a -s option and call
    a sstrip/strip program to do a job.

d80593bc4d fix for the bcheck.o (bug #14958)
- care about __attribute__ redefinition in the system headers
    - an invalid pointer must be returned when (addr >= e->size),
      and not (addr > e->size)

    A test program:
    #include <stdio.h>
    #include <stdlib.h>
    int main ()
    {
	int v[10];
	fprintf(stderr, "&v[0]  = %p\n", &v[0]);
	fprintf(stderr, "&v[10] = %p\n", &v[10]);
	exit(1);
	return 0;
    }
    // tcc -b test.c

    The output before a patch:
    &v[0]  = 0xbf929d8c
    &v[10] = 0xbf929db4

    The output after a patch:
    &v[0]  = 0xbff6e33c
    &v[10] = 0xfffffffe

25b2779c3d x86-64: Fix stdarg for large non-float structs
Some structs are passed in registers.  When they need more than
one the implementation of __va_arg on x86-64 didn't correctly account
for this.  This fixes only the cases where the structs consist of
integer types, as there the register save area is consecutive.

Fixes some tests from 73_arm64.c, but still leaves those failing
that use floating point in the large-but-regpassed structs.

50899e30ab Fix stack overwrite on structure return
The common code to move a returned structure packed into
registers into memory on the caller side didn't take the
register size into account when allocating local storage,
so sometimes that lead to stack overwrites (e.g. in 73_arm64.c),
on x86_64.  This fixes it by generally making gfunc_sret also return
the register size.
