Hi all, I'm dealing with the multi-threaded code, in one of executions of the program I hitting an assertion failure, I'm not always getting the assertion failure when I run the executable but it occurs for say (1 in 10) times. I think there may be an thread race condition. I don't know which is the root cause of this error because the assertion not explicitly occurs in my code, it

This should be fixed in 5044196b412f. That helped a bit, but not yet fully. Looks like it might be still reachable memory, so leakcheck isn't that helpful. Oooh. I think I see. For various reasons the symbol names we

Hi Andres, Ok -- I've added some API for this in 438db0719681: You can get the string pool from the execution session with LLVMOrcExecutionSessionGetSymbolStringPool, then clear that with LLVMOrcSymbolStringPoolClearDeadEntries. -- Lang.

The function comments for modules say that: /** *

I haven't tested it, but it looks to me like llvm-profdata merge (well, InstrProfWriter specifically) would not have deterministic output. Certainly the textual output iterates over FunctionData which is a StringMap of SmallDenseMaps, neither of which has deterministic iteration. The binary writing looks like it'd have similar issues - looping through these unordered maps & writing

Hi all, I can compile LLVM+clang (from svn 2.8 branch, fyi) just fine with gcc 4.4.5 and 4.5.1 on Linux/amd64 just fine, and I did successfully built LLVM+clang on Solaris10/amd64 (32bit built) just fine with gcc 3.3, too. However, when it comes to compiling my *own* project that builds atop of LLVM, I'm getting a strange compilation error when using GCC 4.5.1 but *NOT* when using GCC 4.4.5

I see. Using two comdats would still cause the same problem for us, no? So the

Hi List, My IR compiles fine and runs. I've tried to add DebugIR pass so as to be able to debug and profile it (since source is an SQL query all that I can debug and profile is IR itself). When I tried to add it to pass manager I got the following assert: Program received signal SIGABRT, Aborted. 0x00007ffff3fe4425 in __GI_raise (sig=<optimized out>) at

TL;DR: If you use metadata (especially if it's out-of-tree), check the numbered list of lost functionality below to see whether I'm trying to break your compiler permanently. In response to my recent commits (e.g., [1]) that changed API from `MDNode` to `Value`, Eric had a really interesting idea [2] -- split metadata entirely from the `Value` hierarchy, and drop general support for
