dump_cpu is used only when DEBUG is defined.
Fixes the following GCC warning on builds without DEBUG defined.
util/u_cpu_detect.c:76: warning: 'debug_get_option_dump_cpu' defined but not used
check_os_katmai_support checks that the operating system running on a
SSE-capable processor supports SSE. This is necessary for unpatched
2.2.x and earlier kernels. 2.4.x and later kernels support SSE.
check_os_katmai_support will disable SSE capabilities for 32-bit x86
operating systems for which there is no code path. Currently, this
function handles Linux, Windows, and several BSDs. Mac OS, Cygwin, and
Solaris are several operating systems with no code paths.
Rather than add code for the unhandled operating systems, remove this
function altogether. This will fix SSE detection on all recent 32-bit
x86 operating systems. This completely breaks functionality on unpatched
2.2.x and earlier kernels, although there are likely no Gallium3D users
on such operating systems.
This commit silences the printing off most of the debug information
when running debug builds. The big culprits are: the tgsi sanity checker
that gets run on all shaders on debug; all the options; and
finaly the cpu caps printer.
As we are compiling with -D_BSD_SOURCE, sigjmp_buf and siglongjmp
should be replaced by the non-sig functions (see man 3 setjmp).
Tested on linux/cell.
Fixes a segfault and better code. Unfortunately using an arbitrary
register ("=r") causes the gcc to abort when the code is optimized saying
it can't satisfy the constraint. Setting seems to do the trick.
I was waiting for the need to use this code to arise, and it finally came.
I've tested building this on Linux and Windows, both x86 and x64_64. But
it might break other platforms. Please bear with me and help me fix it.
Many thanks to Dennis Smit who submitted this, and Eric Anholt whose
work this was based on.
It still needs a slight code massasing to integrate with the rest of
gallium (namely mapping the OS_* ARCH_* defines), but I'm commiting anyway
so that it is available to be used when somebody needs it.
