From 44cb65fff1fa26a2a1ff90290f172756f082c8a1 Mon Sep 17 00:00:00 2001 From: Tom Roeder Date: Thu, 5 Jun 2014 19:29:43 +0000 Subject: Add a new attribute called 'jumptable' that creates jump-instruction tables for functions marked with this attribute. It includes a pass that rewrites all indirect calls to jumptable functions to pass through these tables. This also adds backend support for generating the jump-instruction tables on ARM and X86. Note that since the jumptable attribute creates a second function pointer for a function, any function marked with jumptable must also be marked with unnamed_addr. llvm-svn: 210280 --- llvm/lib/Bitcode/Reader/BitcodeReader.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'llvm/lib/Bitcode/Reader/BitcodeReader.cpp') diff --git a/llvm/lib/Bitcode/Reader/BitcodeReader.cpp b/llvm/lib/Bitcode/Reader/BitcodeReader.cpp index 7b018a6..41d1f06 100644 --- a/llvm/lib/Bitcode/Reader/BitcodeReader.cpp +++ b/llvm/lib/Bitcode/Reader/BitcodeReader.cpp @@ -549,6 +549,8 @@ static Attribute::AttrKind GetAttrFromCode(uint64_t Code) { return Attribute::InlineHint; case bitc::ATTR_KIND_IN_REG: return Attribute::InReg; + case bitc::ATTR_KIND_JUMP_TABLE: + return Attribute::JumpTable; case bitc::ATTR_KIND_MIN_SIZE: return Attribute::MinSize; case bitc::ATTR_KIND_NAKED: -- cgit v1.1
