various stuff win32/Makefile ("for cygwin") removed - On cygwin, the normal ./configure && make can be used with either cygwin's "GCC for Win32 Toolchain" ./configure --cross-prefix=i686-w64-mingw32- or with an existing tcc: ./configure --cc=<old-tccdir>/tcc.exe tcctest.c: - exclude test_high_clobbers() on _WIN64 (does not work) tests2/95_bitfield.c: - use 'signed char' for ARM (where default 'char' is unsigned) tests: - remove -I "expr" diff option to allow tests with busybox-diff. libtcc.c, tcc.c: - removed -iwithprefix option. It is supposed to be combined with -iprefix which we don't have either. tccgen.c: - fix assignments and return of 'void', as in void f() { void *p, *q; *p = *q: return *p; } This appears to be allowed but should do nothing. tcc.h, libtcc.c, tccpp.c: - Revert "Introduce VIP sysinclude paths which are always searched first" This reverts commit 1d5e386b0a78393ac6b670c209a185849ec798a1. The patch was giving tcc's system includes priority over -I which is not how it should be. tccelf.c: - add DT_TEXTREL tag only if text relocations are actually used (which is likely not the case on x86_64) - prepare_dynamic_rel(): avoid relocation of unresolved (weak) symbols tccrun.c: - for HAVE_SELINUX, use two mappings to the same (real) file. (it was so once except the RX mapping wasn't used at all). tccpe.c: - fix relocation constant used for x86_64 (by Andrei E. Warentin) - #ifndef _WIN32 do "chmod 755 ..." to get runnable exes on cygwin. tccasm.c: - keep forward asm labels static, otherwise they will endup in dynsym eventually. configure, Makefile: - mingw32: respect ./configure options --bindir --docdir --libdir - allow overriding tcc when building libtcc1.a and libtcc.def with make XTCC=<tcc program to use> - use $(wildcard ...) for install to allow installing just a cross compiler for example make cross-arm make install - use name <target>-libtcc1.a build-tcc.bat: - add options: -clean, -b bindir

The important thing is to check them *BEFORE* they are loaded into registers. New function gbound_args() does that. In any case, code instrumentation with the bounds-check functions as such now seems to work flawlessly again, which means when they are inserted as NOPs, any code that tcc can compile, seems to behave just the same as without them.
