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

[LLVMdev] Adding sample profile support to llvm-profdata?
Duncan, Justin,
I'm about to submit a series of patches that add writing capabilities for
sample profiles in both text and binary formats. Soon, I'll add a third
format (to make it interoperable with GCC).
I would like to add some profile maintenance utilities as well: merging,
dumping and converting.
It seems like the best place would be tools/llvm-profdata. But that means

It did improve the situation significantly, thanks!
There's still a smaller leak, unfortunately. The function comments for
modules say that:

[LLVMdev] hacking clang IdentifierTable
Hi all,
Clang use a hash table to store all its identifiers. The hash table
definition is:
typedef llvm::StringMap<IdentifierInfo*, llvm::BumpPtrAllocator>
HashTableTy;
HashTableTy HashTable;
Can anyone explain the mechnism of handling the name string key collision
for me? Is there a IdentifierInfo objects chain or list for
variable or function with the same name?
Thanks very much!

[LLVMdev] Prevent unbounded memory consuption of long lived JIT processes
This series of patches address several issues causing memory usage to grow
indefinetely on a long lived process.
These are not convenional leaks -- memory would have been freed when the LLVM
context or/and JIT engine is destroyed -- but for as long as they aren't the
memory is usage effectively ubounded.
The issues were found using valgrind with '--show-reachable=yes' option:

profiles, profdata & homes
Hello,
Due the trees, I can't see the forest.
I understand the concept of home directories on the file server
becoming a share for the user on the smb-client computer.
I have a vague idea of "profiles", but I'm lost at "profdata".
How does that last one fit in? Where can I read more about it?
(profdata is common keyword on the search engines)

confused about directory permissions for profdata
This week I migrated out main server from Fedora 8 to Fedora 11. It
has been a stressful time, but things are mostly working. Samba and
LDAP weren't really a problem, but I've beat down the list of problems
to something Samba related.
(For the benefit of anyone else going this route, the biggest problem
by far was iptables. Maybe we had it turned off under FC8, but I

InstrProf backward compatibility
Hi all,
I am working on adding PGO to LDC (LLVM D Compiler). The current
implementation
1) uses LLVM's InstrProf pass to generate an instrumented executable
2) links to compiler-rt/lib/profile for the runtime functionality to write
a raw profile data file
3) uses llvm-profdata to merge profile data and convert from profraw to
profdata format
4) uses llvm::IndexedInstrProfReader to read-in

Struggling with a PGO build of clang -- llvm-profdata was built without zlib support?
Hi!
I'm trying to build a fast Clang for myself to use for debug builds on
Clang itself, but I've been struggling for a very long time on it. Could
you please help?
I've been following this guide: https://llvm.org/docs/HowToBuildWithPGO.html
I've quickly learned that its outdated, because the script it talks about
doesn't work with the monorepo layout at all, but in any

Yes, that was it! Now that I took a closer look, the guide also states that
I should use the stage2 build. Silly me.
Thanks!

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.

[PATCH 0/5] Fix SELinux
We can use the setfiles(8) command to relabel the guest filesystem,
even though we don't have a policy loaded nor SELinux enabled in the
appliance kernel.
This also deprecates or removes the old and broken SELinux support.
This patch isn't quite complete - I would like to add some tests to
the new API. I'm posting here to garner early feedback.
Rich.
