llvm dev - Nov 2011 - [LLVMdev] bdver1 cpu(bulldozer) support with dragonegg

Hello,
if I compile with dragonegg and -march=native I get this message:
'bdver1' is not a recognized processor for this target (ignoring
processor)
Is there any plan to support this cpu ?


Here the full example the source file doesn't matter.

gcc -s -static -Wall -O2 -march=native -fplugin=dragonegg.so
-fplugin-arg-dragonegg-enable-gcc-optzns    pointer.c   -o pointer
'bdver1' is not a recognized processor for this target (ignoring
processor)

Hi Jan,

this is coming directly from LLVM which doesn't know about bulldozer yet.

I don't know.  Hopefully someone who knows something about this will
comment.

Ciao, Duncan.

I added a basic description for bdver1 and bdver2 in r145493.
LLVM doesn't know many of bulldozer's new instructions though.

We have some bulldozer tunings we'll push back as soon as we can get
upgraded to 3.0.  Might be a few months, though.  In the meantime,
simply adding the target wouldn't be very difficult.
