I'm using a recent revision of TOT (280704) to build clang/LLVM for
PowerPC64 little endian. I'm getting an assembler error when building
PPCInstPrinter.cpp:
The error is:
/tmp/PPCInstPrinter-84c835.s: Assembler messages:
/tmp/PPCInstPrinter-84c835.s:7671: Error: operand out of range
(0x0000000000008004 is not between 0xffffffffffff8000 and
0x0000000000007ffc)
The offending line is the bne branch in this snippet:
.LBB24_787:
ld 3, 16(29)
ld 4, 24(29)
sub 4, 4, 3
rldicl 4, 4, 60, 4
cmplwi 0, 4, 3
bne 0, .LBB24_2630
Could this be because of a recent change in the PowerPC code generator
or just because PPCInstPrinter.cpp changed a bit and exposed a
pre-existing bug?
