llvm intrinsics in llvm-gcc-4.2.  This is because
get_pointer_alignment bails out: it relies on TER
to compute accurate alignment information.

This hopefully fixes a miscompilation of TargetData.cpp when self hosting.

clearly shared between processors if these instructions are being used, no 
further specification of what type of memory is necessary.

weeks.

but I think it got lost in the conversion mess.

403.gcc from 15.2s to 14.3s.

code that cross integer / floating point domains (e.g. generate pxor / pand for
logical ops on floating point value, movdqa to load / store floating point SSE
values). Given that, it's better to use movaps instead of movdqa and movups
instead of movdqu. They have the same latency but the "aps" variants are one
byte shorter.
If the domain crossing problem is a real performance issue, then we will have to
fix it with dynamic programming based isel.

Fix patterns so we isel the xorps, etc. for floating pt logical SSE ops. DAG combiner may fold away the (bit_convert (load)).

Change the keywords for the zext and sext parameter attributes to be 
zeroext and signext so they don't conflict with the keywords for the
instructions of the same name. This gets around the ambiguity.

llvm-svn: 40069

the type "unsigned" instead of uintptr_t for a 1-bit structure field.

with hopefully correct code that pleases g++-4.2.

nowadays, unfortunately it's not so easy to get good
code here while still producing correct code in exotic
situations.

With this, the time to optimize 403.gcc is down to 15.1s.

llvm-svn: 40042

llvm-svn: 40041

This results in a slight speedup for 403.gcc.
