Subject: gdbserver optimizer build failure
Date: Fri, 18 Jun 2010 20:57:00 -0000 [thread overview]
Message-ID: <000f01cb0f28$e3d8b610$ab8a2230$@muller@ics-cnrs.unistra.fr> (raw)
gdbserver build currently
fails on gcc16 (x86-64 machine running linux).

The build completes successfully!
It seems that there is a problem with the macro EMIT_ASM
which seems to be mistreated by the optimizer.
I have no clue how to solve this...
