I obviously should not post to mailing lists before I've eaten. With my
"fix" I get an assertion when taking an address of a f...

[LLVMdev] PowerPC instruction cache invalidation
Hi all,
When you genetate code on PowerPC you need to explicitly invalidate
the instruction cache to force the processor to reread it. In LLVM
there is code to do this for function stubs on Macintosh, but not
for other platforms and not for JITted code generally.
The attached patch adds support for GNU platforms, but I can't figure
out a nice way to call it for all generated code. Can
