* [X86] Don't extend v16i8 non-uniform shifts to v16i32 if we have BWI. Use ↵Craig Topper2017-12-191-1/+3
| | | | | | | | v16i16 instead. BWI supports shifting by word amounts. Even if VLX isn't support we can still widen to v32i16 and extract the lower half. For SKX its preferrable to not use 512-bit vector if we can. llvm-svn: 321059
* [X86] Use a specific list of MVTs in combineShiftRightArithmetic instead of ↵Craig Topper2017-12-191-2/+2
| | | | | | | | iterating over every integer VT and checking their size. Previously, we were checking for MVTs with sizes betwen 8 and 64 which only includes i8, i16, i32, and i64 today. But I don't think we should assume that and should list the types that are legal for x86. I also don't think we need i64 since type legalization is guaranteed to split those up. llvm-svn: 321058

* [X86] Use ZERO_EXTEND instead of ANY_EXTEND when extending the shift amount ↵Craig Topper2017-12-191-1/+1
| | | | | | | | | | for a non-uniform shift. My reading of the SDM says that all bits of the shift amount are used. If the value of the element is larger than the number of bits the result the shift result is zero. So I think we need to zero_extend here to avoid garbage in the upper bits. In reality we lower any_extend as zero_extend so in most cases it would be hard to hit this. llvm-svn: 321055
* Fix APFloat from string conversion for InfSerguei Katkov2017-12-192-3/+3
| | | | | | | | | | | | | | | | | | The method IEEEFloat::convertFromStringSpecials() does not recognize the "+Inf" and "-Inf" strings but these strings are printed for the double Infinities by the IEEEFloat::toString(). This patch adds the "+Inf" and "-Inf" strings to the list of recognized patterns in IEEEFloat::convertFromStringSpecials(). Re-landing after fix.

* Fix buffer overrun in WindowsResourceCOFFWriter::writeSymbolTable()Bob Haarman2017-12-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We were using sprintf(..., "$R06X", <some uint32_t>) to create strings that are expected to be exactly length 8, but this results in longer strings if the uint32_t is greater than 0xffffff. This change modifies the behavior as follows: - Uses the loop counter instead of the data offset. This gives us sequential symbol names, avoiding collisions as much as possible. - Masks the value to 0xffffff to avoid generating names longer than 8 bytes. - Uses formatv instead of sprintf.

* [Analysis] Generate more precise TBAA tags when one access encloses the otherIvan A. Kosarev2017-12-181-6/+17
| | | | | | | | | | | | | | There are cases when two tags with different base types denote accesses to the same direct or indirect member of a structure type. Currently, merging of such tags results in a tag that represents an access to an object that has the type of that member. This patch changes this so that if one of the accesses encloses the other, then the generic tag is the one of the enclosed access.

* [PGO] Fix handling of cold entry count for instrumented PGOTeresa Johnson2017-12-182-2/+7
| | | | | | | | | | | | | | | | | | | | | Summary: In r277849, getEntryCount was changed to return None when the entry count was 0, specifically for SamplePGO where it means no samples were recorded. However, for instrumentation PGO a 0 entry count should be returned directly, since it does mean that the function was completely cold. Otherwise we end up treating these functions conservatively in isFunctionEntryCold() and isColdBB(). Instead, for SamplePGO use -1 when there are no samples, and change getEntryCount to return None when the value is -1.
