Hans Wennborg f6eeeaf04e Revert "[PM/CC1] Add -f[no-]split-cold-code CC1 option to toggle splitting" ... This broke Chromium's PGO build, it seems because hot-cold-splitting got turned on unintentionally. See comment on the code review for repro etc. > This patch adds -f[no-]split-cold-code CC1 options to clang. This allows > the splitting pass to be toggled on/off. The current method of passing > `-mllvm -hot-cold-split=true` to clang isn't ideal as it may not compose > correctly (say, with `-O0` or `-Oz`). > > To implement the -fsplit-cold-code option, an attribute is applied to > functions to indicate that they may be considered for splitting. This > removes some complexity from the old/new PM pipeline builders, and > behaves as expected when LTO is enabled. > > Co-authored by: Saleem Abdulrasool <compnerd@compnerd.org> > Differential Revision: https://reviews.llvm.org/D57265 > Reviewed By: Aditya Kumar, Vedant Kumar > Reviewers: Teresa Johnson, Aditya Kumar, Fedor Sergeev, Philip Pfaffe, Vedant Kumar This reverts commit 273c299d5d649a0222fbde03c9a41e41913751b4.		2020-10-19 12:31:14 +02:00
