Hi,
X86_TUNE_GENERAL_REGS_SSE_SPILL: Try to spill general regs to SSE regs instead
of memory.
I tried enabling the above tuning with -march=bdver4 -Ofast
-mtune-ctrl=general_regs_sse_spill.
I did not find any code differences.
Looking at the below code to enable this tune, mmx ISA needs to b

And don't forget that --enable-threads=win32 also enables emulated TLS, which
is completely unnecessary if we have some kind of TLS support.
Because pthread_key_create() requires a destructor, TLS must still be emulated
on x86 because there is no native support. The fiber local storage (FLS) API
Currently, --enable-threads=win32 map to gthr-win32.{h|c}, could we map

Yes I learnt those *ByAddress* functions a few months ago and was shocked that
Microsoft had plagiarized futex from Linux.
As you have pointed out already, those APIs are only available on Windows 8
and later.
If we need fuex semantics on Windows 7 and earlier, we must simulate it.

Hello,
I bring to your attention SafeStack, part of a bigger research project
- CPI/CPS [1], which offers complete protection against stack-based
control flow hijacks. I am interested in developing SafeStack for GCC
and I would like to ask for your feedback on this proposal.
SafeStack is a secur
Thanks for your reply. :>
However I am still having problems building GCC. (Yesterday stage 1 was ok, but
during stage 2 autoconf just failed to find any standard headers. I am still
struggling with it.)
Once I build gcc successfully I will have a look at that configure.ac. Wish me
luck. (btw t

Hi all,
The 'win32' thread model of gcc has been there since long long ago, being
compatible with very old Windows versions, also having a number of drawbacks:
0) its implementation is very inefficient, and
1) its mutexes and condition variables require dynamic initialization and are
