b56edc7b90 Several multiarch/biarch fixes
* Add multiarch directories for arm and i386
* Fix detection of biarch: /lib64/ld-linux-x86-64.so.2 is mandated by
  ABI and is thus always present, even if there is no biarch
* Define CONFIG_LDDIR directly with the right value in case of multiarch
  instead of defining it to /lib and then redifining it.

a2c71af1ea Fix CONFIG_LDDIR usage
This patch fix 2 bugs in CONFIG_LDDIR usage:

* CONFIG_LDDIR used for 2 purposes

  there is confusion between the directory to find libraries, crt* files
  and headers and the directory in which the program interpreter is.
  These two directories are not related. The latter is specified by the
  ABI and should not be configurable while the former depends on the
  system (single arch, biarch, multiarch). This end a longstanding issue
  with amd64 program interpreter later propagated to other architecture
  interpreters.

* If multiarch is in effect, then the library directory should be /lib.
  /lib64 denotes biarch architecture, everything which is here would be
  in /lib/x86_64-linux-gnu instead.

0394caf784 Emit spaces for -MD
TCCs make dependency generator is incompatible with the GNU
depcomp script which is widely used.  For TCC it has to go over
the output of -MD, (it detects it as ICC compatible), but the
sed commands it uses are confused by tabs in the output, so that
some rewrites aren't done.

Those tabs will then finally confuse make itself when the
generated .d files are included.  It reads them as goal commands
(leading tab), and is totally lost then.

Short of changing depcomp (hard because distributed with all kinds
of software), simply emit spaces for -MD.

9ca9c82ff8 Fix comparing comparisons
Sometimes the result of a comparison is not directly used in a jump,
but in arithmetic or further comparisons.  If those further things
do a vswap() with the VT_CMP as current top, and then generate
instructions for the new top, this most probably destroys the flags
(e.g. if it's a bitfield load like in the example).

vswap() must do the same like vsetc() and not allow VT_CMP vtops
to be moved down.

718fd591fa Make sizeof() be of type size_t
This matters when sizeof is directly used in arithmetic,
ala "uintptr_t t; t &= -sizeof(long)" (for alignment).  When sizeof
isn't size_t (as it's specified to be) this masking will truncate
the high bits of the uintptr_t object (if uintptr_t is larger than
uint).

15f4ac2b1a Fix detection of labels with a typedef name
This needs to be accepted:
  typedef int foo;
  void f (void) { foo: return; }
namespaces for labels and types are different.  The problem is that
the block parser always tries to find a decl first and that routine
doesn't peek enough to detect this case.  Needs some adjustments
to unget_tok() so that we can call it even when we already called
it once, but next() didn't come around restoring the buffer yet.
(It lazily does so not when the buffer becomes empty, but rather
when the next call detects that the buffer is empty, i.e. it requires
two next() calls until the unget buffer gets switched back).

1d0a5c2515 x86_64: Fix segfault for global data
When offsetted addresses of global non-static data are computed
multiple times in the same statement the x86_64 backend uses
gen_gotpcrel with offset, which implements an add insn on the
register given.  load() uses the R member of the to-be-loaded
value, which doesn't yet have a reg assigned in all cases.

So use the register we're supposed to load the value into as
that register.

86ac6b9bee x86_64: Fix indirection in struct paramaters
The first loop setting up struct arguments must not remove
elements from the vstack (via vtop--), as gen_reg needs them to
potentially evict some argument still held in registers to stack.

Swapping the arg in question to top (and back to its place) also
simplifies the vstore call itself, as not funny save/restore
or some "non-existing" stack elements need to be done.

Generally for a stack a vop-- operation conceptually clobbers
that element, so further references to it aren't allowed anymore.

ab936aeb8c cleanup some partially broken patches
- tests/Makefile:
  fix commit de54586d5b
  This hunk it unrelated to the other changes (which are about MacOSX).
  It is not useful and partially wrong.  Optional tests are meant to
  stay optional, btest would work only for i386

- tcc.h:
  fix commit c52d79605a by unknown
  The message says it's for MINTW but the patch has obviously
  no effect for MINGW (which defines __GNUC__).  However the patch
  seems useful for MSC which however needs _strto(u)i64 with underscore.

de54586d5b Further changes improving the OSX build. Everything builds. libtest passes.
Other tests still have issues, currently with weak linking.

One of the primary stumbling blocks on OSX is the lack of support for
mach-o binaries. Therefore all tcc usage on OSX has to be limited to elf
binaries, presumably produced by tcc itself.

Therefore I had to enable building of tiny_libmaker for OSX. Then changed
the make to use tcc and tiny_libmaker to compile the tcclib1.

In order to compile the tests, specifically the parts that use weak linking,
I have had to define MACOSX_DEPLOYMENT_TARGET to 10.2, which seems like a
hack, but extensive searching seems to indicate that this is the only way
to make apple gcc allow weak linking. Using any other value, bigger or smaller
breaks weak linking.

Also added _ANSI_SOURCE define required by some OSX headers, and some cosmetic
gitignore changes. I believe these changes should not impact other platforms.

a0db7162af Fix assumption of 32bit long on portions of Elf
Modify tcc to accept convert full 64bits of specified text section
when converting on Win64. Write high bytes to the elf section address
as well. This allows creation of elf binaries located in offsets using
full 64 bit addresses.

e343b1dfd4 Add __REDIRECT needed for Large File Support API on linux
Since commit 9b09fc3 ("Add support of asm label for functions",
05-09-2010) tcc has had the capability to rename functions at the
assembly level. This capability was subsequently used by commit
2596273 ("Add support for __REDIRECT_NTH needed with eglibc",
11-09-2010) to redirect long double functions on platforms which
did not support long double.

Here we add the companion macro __REDIRECT which is used (along
with __REDIRECT_NTH) in the glibc headers on Linux to support the
Large File API (when _FILE_OFFSET_BITS is set to 64).

d7a7c3769d Multiple fixes for 64 bit sections
This changeset attempts to fix a few problems when giving using
the high 32bits of a 64bit section offset. There are likely more
issues (or perhaps regressions) lurking in the muck here. In general,
this moves a few data type declarations to use uplong.  Also, add
support for 64bit mingw32 building under cygwin.  Because native
types are used for 64 bit offsets, this won't fix challenges with
cross compiling from 32bit -> 64bit.

Tested under cygwin, against binary compiled with
-Wl,-Ttext=0xffffff8000000000

6e13c35334 Attempt to fix 32 bit OSX build. The fix consists of adding -m32 and -m64
to the appropriate CFLAGS. In addition, memory hooks are very different
on OSX, so build of bcheck.c had to be disabled for now.

Change of the CFLAGS does affect builds on other platforms, and this needs
to be tested.

8ca8b08890 Patch attempting to build OSX TinyCC.
Applied patch found on stackoverflow (link below). I also found some
related changes that looked like logically needed. The stackoverflow
changes addressed only two registers which were breaking a compile.
However reading the code in the same file shows two other register
accesses that, while not breaking the build, should have the same fix.

http://stackoverflow.com/questions/3712902/problems-compiling-tcc-on-os-x/3713144#3713144

The test driver was changed by changing 'cp -u' into 'cp' as '-u' is not
supported on mac osx.

I found that osx build required the WITHOUT_LIBTCC define. I suspect the
reason for this is tcc unability to handle mach-o files. In order to
properly address this I had to change 'configure' to propagate target os
name to Makefile.

Current state is that simple tests work, but not the whole 'make test'
suite runs.

To the best of my knowledge, these changes should not impact other
platforms.
