Subject: [PATCH 0/3] fixes for CLANG35 on ARM
Date: Wed, 12 Dec 2018 11:33:05 +0100 [thread overview]
Message-ID: <20181212103308.8099-1-ard.biesheuvel@linaro.org> (raw)
Building with Clang 3.5 for ARM may result in build breakage, due to the
fact that it may emit non-adjacent movw/movt instructions pairs which
cannot be relocated in PE/COFF. We pass -mno-movt in some places to
work around a related issue in the relocatable PrePi in ArmVirtPkg, but
we need to disable movw/movt entirely to really address this issue.
So first, fix some breakage that results from building with -mlong-calls
in the optimized BaseMemoryLib code (#1)
Patch #2 switches to -mkernel, which disables movw/movt generation (and
enabled -mlong-calls as a side effect)
Patch #3 removes the now redundant, and incompatible command line
overrides for the relocatable PrePi.
