From 68c91994931c29dfc7a09e7d5a5e4515d13b12bd Mon Sep 17 00:00:00 2001 From: Amy Huang Date: Wed, 24 Apr 2019 23:02:48 +0000 Subject: Recommitting r358783 and r358786 "[MS] Emit S_HEAPALLOCSITE debug info" with fixes for buildbot error (undefined assembler label). Summary: This emits labels around heapallocsite calls and S_HEAPALLOCSITE debug info in codeview. Currently only changes FastISel, so emitting labels still needs to be implemented in SelectionDAG.
