[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences 2020-12-31T08:27:11+00:00 Fangrui Song i@maskray.me 2020-12-31T08:27:11+00:00 fd739804e0591468762eb87488a497a3f7d4afb0 For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -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 `{{.*}} `.

To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition,
which sets dso_local for default visibility external linkage definitions.

Fix debug info for NoDebug attr 2020-05-21T13:02:56+00:00 Yaxun (Sam) Liu yaxun.liu@amd.com 2020-05-15T03:09:30+00:00 361e4f14e35981e7498a38ab7c31da7fb7414fb8 NoDebug attr does not totally eliminate debug info about a function when inlining is enabled. This is inconsistent with when inlining is disabled. This patch fixes that. Differential Revision: https://reviews.llvm.org/D79967 
NoDebug attr does not totally eliminate debug info about a function when
inlining is enabled. This is inconsistent with when inlining is disabled.

This patch fixes that.
