Subject: [MCJIT] Teach RuntimeDyldChecker to handle underscores at the start of symbols.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=f072ab78ee3845725668c0ef8b4da598e1af9788;ds=sidebyside

[MCJIT] Teach RuntimeDyldChecker to handle underscores at the start of symbols.

RuntimeDyldChecker had been testing isalpha(Expr[0]) to recognise symbol tokens,
and throwing unrecognized token errors when it hit symbols with leading
underscores. This fixes that.
