I get the feeling I am missing some background.
Which architecture is this?
Are the ports already upstream in binutils/gas/gcc?
No. Working on it. Out-of-tree source can be found on
Do you also have a new elfutils ebl backend for it?
No. Just started fiddling on that yesterday.
After your changes, how well does the testsuite work?
glibc works great, almost everything passes. elfutils, no clue.
Really, the goal here was to get perf working on the kernel.
I am a little afraid the configure logic might become somewhat
Ulrich's suggestion to just use a different syntax for
your instruction set does make sense to me.
I'll give it a shot. The fear was that the blizzard of
equals signs already being used to mean something
