Hello Andy,
I have tested your patch concerning RTL prologue/epilogue. Gratulations: My
testsuite run only reports a single regression
Tests that now fail, but worked before:
gcc.c-torture/execute/20010122-1.c execution, -O0
. This happens on a testcase that anyway is problematic (succeeds only for
selected set of optimization switches).
Due to your "rjmp" trick the resulting code also is sligtly tighter. IIUC, now
there is also hope for optimizing sequences like
call other_function
ret
to
jmp other_function
.?
Yours,
Björn
