Bug ID: 65574
Summary: assembler options don't match predefined macros
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: amodra at gmail dot com
Seen when compiling glibc with a freshly built powerpc64le gcc configured
without --with-cpu.
cat > ledefault.S <<EOF
/* from glibc/sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontex.S */
#ifdef _ARCH_PWR6
mtfsf 0xff,0,1,0
#endif
EOF
gcc -c ledefault.S
ledefault.S: Assembler messages:
ledefault.S:3: Error: junk at end of line: `1,0'
By default the assembler is invoked with -mppc64, and -many doesn't help since
that won't add the four operand form of mtfsf to the opcode hash when there is
an existing two operand mtfsf.
