Subject: [ARM] Remove dead code from ARMConstantIslands.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1396e0fa82aeddedbe5f36aec16b3e520e73f66b;p=llvm

[ARM] Remove dead code from ARMConstantIslands.

tLDRHi is not a pc-relative load; it can't directly refer to a
constant pool or jump table.
