From 80a75bfae980df96f969f1c05b0c4a80ce975240 Mon Sep 17 00:00:00 2001 From: Gordon Henriksen Date: Mon, 10 Dec 2007 03:18:06 +0000 Subject: Adding a collector name attribute to Function in the IR. These methods are new to Function: bool hasCollector() const; const std::string &getCollector() const; void setCollector(const std::string &); void clearCollector(); The assembly representation is as such: define void @f() gc "shadow-stack" { ... The implementation uses an on-the-side table to map Functions to collector names, such that there is no overhead. A StringPool is further used to unique collector names, which are extremely likely to be unique per process. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44769 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Bitcode/LLVMBitCodes.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/llvm/Bitcode') diff --git a/include/llvm/Bitcode/LLVMBitCodes.h b/include/llvm/Bitcode/LLVMBitCodes.h index f62af5e17c..32311b26d9 100644 --- a/include/llvm/Bitcode/LLVMBitCodes.h +++ b/include/llvm/Bitcode/LLVMBitCodes.h @@ -58,7 +58,9 @@ namespace bitc { MODULE_CODE_ALIAS = 9, /// MODULE_CODE_PURGEVALS: [numvals] - MODULE_CODE_PURGEVALS = 10 + MODULE_CODE_PURGEVALS = 10, + + MODULE_CODE_COLLECTORNAME = 11 // COLLECTORNAME: [strchr x N] }; /// PARAMATTR blocks have code for defining a parameter attribute set. -- cgit v1.2.3
