2007-12-25GC poses hazards to the inliner. Consider:Gordon Henriksen
define void @f() { ... call i32 @g() ... } define void @g() { ... } The hazards are: - @f and @g have GC, but they differ GC. Inlining is invalid. This may never occur. - @f has no GC, but @g does. g's GC must be propagated to @f. The other scenarios are safe: - @f and @g have the same GC. - @f and @g have no GC. - @g has no GC. This patch adds inliner checks for the former two scenarios. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45351 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-10Adding a collector name attribute to Function in the IR. These Gordon Henriksen
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

2007-09-17Fix for PR1633: Verifier doesn't fully verify GC intrinsicsGordon Henriksen
LLVM now enforces the following prototypes for the write barriers: <ty>* @llvm.gcread(<ty2>*, <ty>**) void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**) And for @llvm.gcroot, the first stack slot is verified to be an alloca or a bitcast of an alloca. Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42051 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-07Split eh.select / eh.typeid.for intrinsics into i32/i64 versions. This is ↵Anton Korobeynikov

2007-08-04This is the patch to provide clean intrinsic function overloading support in ↵Chandler Carruth
LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-31Change the x86 assembly output to use tab characters to separate theDan Gohman
mnemonics from their operands instead of single spaces. This makes the assembly output a little more consistent with various other compilers (f.e. GCC), and slightly easier to read. Also, update the regression tests accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40648 91177308-0d34-0410-b5e6-96231b3b80d8
