Subject: Fix r232466 by adding 'i' to the mappings for inline assembly memory constraints.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=06c5d245a2dbad6652ca9ffa262edc169d3fd0d4

Fix r232466 by adding 'i' to the mappings for inline assembly memory constraints.

It's not completely clear why 'i' has historically been treated as a memory
constraint. According to the documentation, it represents a constant immediate.
