Chandler Carruth [Mon, 30 Jan 2012 23:47:44 +0000 (23:47 +0000)]
Chris's constant data sequence refactoring actually enabled printing
vectors of all one bits to be printed more cleverly in the AsmPrinter.
Unfortunately, the byte value for all one bits is the same with
-fsigned-char as the error return of '-1'. Force this to be the unsigned
byte value when returning it to avoid this problem, and update the test
case for the shiny new behavior.

desire this change. It seems good on the surface, and certainly intended
based on the code written.

Add support for the R_ARM_TARGET1 relocation, which should be given to relocations applied to all C++ constructors and destructors.

This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against.

12 years agoFix for the following bug in AVX codegen for double-to-int conversions:
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.

The patch includes changes in the .td file, LIT test for the changes and a fix in a legacy LIT test (which produced asm code conflicting with LLVN IR spec).
