Reid Kleckner	1d9c249db5	Reimplement the bittest intrinsic family as builtins with inline asm ... We need to implement _interlockedbittestandset as a builtin for windows.h, so we might as well do the whole family. It reduces code duplication anyway. Fixes PR33188, a long standing bug in our bittest implementation encountered by Chakra. llvm-svn: 333978	2018-06-05 01:33:40 +00:00
Bruno Cardoso Lopes	afa47c91ce	Support MS builtins using 'long' on LP64 platforms ... This allows for -fms-extensions to work the same on LP64. For example, _BitScanReverse is expected to be 32-bit, matching Windows/LLP64, even though long is 64-bit on x86_64 Darwin or Linux (LP64). Implement this by adding a new character code 'N', which is 'int' if the target is LP64 and the same 'L' otherwise Differential Revision: https://reviews.llvm.org/D34377 rdar://problem/32599746 llvm-svn: 305875	2017-06-21 02:20:46 +00:00
