Since default clang -cc1 for ELF is similarto -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences.To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition,which sets dso_local for default visibility external linkage definitions.To make this flip smooth and enable future (dso_local as definition default),this patch replaces (function) `define ` with `define{{.*}} `,(variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

There maystill be some cases where it is not handled well.Reviewers: peter.smith, rnk, serge-sans-paille, sfertile, jfb, jdoerfertSubscribers: dschuff, jyknight, dylanmckay, nemanjai, jvesely, kbarton, fedor.sergeev, asb, rbar, johnrusso, simoncook, sabuasal, niosHD, jrtc27, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, arphaman, PkmX, jocewei, jsji, Jim, lenary, s.egerton, pzheng, sameer.abuasal, apazos, luismarques, cfe-commitsTags: #clangDifferential Revision: https://reviews.llvm.org/D73865 List of files: /llvm-project-15.0.7/clang/test/CodeGen/xray-attr-list.cpp Sun, 02 Feb 2020 20:23:47 +0000 Fangrui Song <maskray@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGen/xray-attr-list.cpp#20dc6ef7 [XRay][llvm+clang] Consolidate attribute list filesSummary:This change consolidates the always/never lists that may be provided toclang to externally control which functions should be XRay instrumentedby imbuing attributes. The files follow the same format as defined inhttps://clang.llvm.org/docs/SanitizerSpecialCaseList.html for thesanitizer blacklist.We also deprecate the existing `-fxray-instrument-always=` and`-fxray-instrument-never=` flags, in favour of `-fxray-attr-list=`.This fixes http://llvm.org/PR34721.Reviewers: echristo, vlad.tsyrklevich, eugenisReviewed By: vlad.tsyrklevichSubscribers: llvm-commits, cfe-commitsDifferential Revision: https://reviews.llvm.org/D45357llvm-svn: 329543 List of files: /llvm-project-15.0.7/clang/test/CodeGen/xray-attr-list.cpp Mon, 09 Apr 2018 04:02:09 +0000 Dean Michael Berris <dberris@google.com>
