Summary: Crash inside fast register allocator on PowerPC
Product: new-bugs
Version: trunk
Platform: Other
OS/Version: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
With r116206, running llc on the attached IR causes an UNREACHABLE to be
reached:
llc vatest.ll -o foo.s -regalloc=fast -march=ppc32
UNREACHABLE executed!
Stack dump:
0. Program arguments: llc vatest.ll -regalloc=fast -march=ppc32
1. Running pass 'Function Pass Manager' on module 'vatest.ll'.
2. Running pass 'Fast Register Allocator' on function '@testing'
Abort trap: 6 (core dumped)
This seems to be appear only when targeting ppc32, and is a regression relative
to last week.
