From: Bobby R. Bruce Date: Wed, 17 Jun 2020 22:50:28 +0000 (-0700) Subject: util,tests: Added compiler test script X-Git-Tag: v20.1.0.0~463 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=91350dc4d5ae5984fa9e9e463cfa663dc00b8aaa;p=gem5.git util,tests: Added compiler test script This script runs a series of compilations on gem5. The following compilers are tested: clang-9 clang-8 clang-7 clang-6 clang-5 clang-4 clang-3.9 gcc-9 gcc-8 gcc-7 gcc-6 gcc-5 gcc-4.8 (to be dropped soon: https://gem5.atlassian.net/browse/GEM5-218) They are tested by building the following build targets: ARM ARM_MESI_Three_Level Garnet_standalone GCN3_X86 MIPS NULL_MESI_Two_Level NULL_MOESI_CMP_directory NULL_MOESI_CMP_token NULL_MOESI_hammer POWER RISCV SPARC X86 X86_MOESI_AMD_BASE For each, ".opt" and ".fast" compiler build settings are tested. clang-9 and gcc-9 are tested against all targets with each build setting. For the remaining compilers, a random build target is chosen. After the script has run, the output of the tests can be found in "compile-test-out". Docker is required to run this script.
