eopXD	a4bf1b449d	[RISCV] Unify depedency check and extension implication parsing logics ... Originially there are two places that does parsing - `parseArchString` and `parseFeatures`, each with its code on dependency check and implication. This patch extracts common parts of the two as functions of `RISCVISAInfo` and let them 2 use it. Reviewed By: asb Differential Revision: https://reviews.llvm.org/D112359	2021-12-09 21:16:04 -08:00
Fangrui Song	fd739804e0	[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences ... 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 `{{.*}} `.	2020-12-31 00:27:11 -08:00
