- Subject: [PATCH][ARM] Fix -Werror build failure
My previous patch to clean up MOVW support left an unused variable. I
tested building a cross-compiler, but not with -Werror. Others have
reported native bootstrap failing. :(
This patch fixes that problem, and removes the unused variable warning
message.
OK?
