gcc man page says: max-cse-insns: The maximum instructions CSE process before flushing. The default is 1000.
but gcc --param max-cse-insns=1000 gives the following error: cc1: error: invalid parameter 'max-cse-insns' With some googling I found the following patch which seems to have a bug where it uses the parameter max-flow-memory-locations erronously also in place for max-cse-insns http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00249.html -- Summary: man pages refer to nonexisting --param max-cse-insns Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: other AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mikko dot tiihonen at hut dot fi http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26685
