2013-10-07 Paulo Andrade <pcpa@gnu.org> * check/self.c: Extend tests to validate jit_callee_save_p does not cause an assertion on valid arguments, and test extra registers defined on some backends. * configure.ac: Do not ignore environment CFLAGS when checking if need to test runtime configurable options, like use x87 when sse2 is available, arm instruction set instead of thumb, etc. * include/lightning/jit_arm.h: Correct wrong jit_f macro definition. * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h: Correct wrong jit_r macro definition. * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the reserved stack space for integer to/from float conversion. The stack space was also changed to ensure it is 8 bytes aligned. Also, for Solaris x86 in 32 bit mode, an alternate truncr_d was implemented because for some reason it is failing with SIGILL if using the "fisttpl" instructions, that must be available on p6 or newer, but for the sake of making all tests pass, implement a 486 or newer sequence if "sun" is defined.
