Bug ID: 52006
Summary: llvm-jitlink failures on ppc64le-redhat-linux
Product: libraries
Version: trunk
Hardware: Other
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Support Libraries
Assignee: unassignedb...@nondot.org

CC: llvm-bugs@lists.llvm.org
>From discussion with Tom Stellard in #jit on the LLVM discord:
> It looks like changing the host triple from powerpc64le-unknown-linux-gnu to
> ppc64le-redhat-linux causes the failures.
> The error message with your patch is: JIT session error: Slab allocator out
> of memory: request for 0x10000 bytes exceeds remaining capacity of 0x0 bytes

Exactly filling a correctly allocated buffer seems unlikely. A more likely
cause is sys::Process::getPageSize returning 0. I have added extra error checks
in ab5e6e7434eb that should confirm this.
If sys::Process::getPageSize is returning zero on ppc64le-redhat-linux then
this should be investigated: it will prevent the LLVM JIT from working for that
triple.
