Subject: support clang internal assembler when building for arm as thumb2 code
X-Git-Tag: v1.1.21~77
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=dffc20591873ede1ec4b30634fc91ba3daa372eb;p=oweals%2Fmusl.git

support clang internal assembler when building for arm as thumb2 code

the clang internal assembler does not accept assembler options passed
via the usual -Wa mechanism, but it does accept -mimplicit-it directly
as an option to the compiler driver.
