Victor Umansky [Thu, 26 Jan 2012 08:51:39 +0000 (08:51 +0000)]
Fix for the following bug in AVX codegen for double-to-int conversions:
. "fptosi" and "fptoui" IR instructions are defined with round-to-zero rounding mode.
. Currently for AVX mode for <4xdouble> and <8xdouble>  the "VCVTPD2DQ.128" and "VCVTPD2DQ.256" instructions are selected (for .fp_to_sint. DAG node operation ) by AVX codegen. However they use round-to-nearest-even rounding mode.
. Consequently, the conversion produces incorrect numbers.

The fix is to replace selection of VCVTPD2DQ instructions with VCVTTPD2DQ instructions. The latter use truncate (i.e. round-to-zero) rounding mode.
As .fp_to_sint. DAG node operation is used only for lowering of  "fptosi" and "fptoui" IR instructions, the fix in X86InstrSSE.td definition file doesn.t have an impact on other LLVM flows.

Revert a tiny bit of r148553 which extended LLVM's function attributes
to 64-bits, and added a new attribute in bit #32. Specifically, remove
this new attribute from the enum used in the C API. It's not yet clear
what the best approach is for exposing these new attributes in the
C API, and several different proposals are on the table. Until then, we
can simply not expose this bit in the API at all.

which switched from "1 << 31" to "1U << 31" for the top enum. While "1
<< 31" is technically undefined behavior, implementations DTRT here.
However, MS and -pedantic mode warn about non-'int' type enumerator
values. If folks feel strongly about this I can put the 'U' back in, but
