This seems to have broken bootstrap on PowerPC. I originally saw it on AIX, but duplicated it on PPC64LE Linux.
The failure is genoutput seems to be miscompiled by stage1 and produces error messages implying that it did not parse rs6000/vsx.md correctly. I don't know if the miscompilation is genoutput sources or libstdc++. /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sr>,?<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 0 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 0 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sr>,<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 1 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 1 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sr>,<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 2 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 2 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sr>,<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 3 /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1299: note: in operand 3 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sr>,?<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 0 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 0 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sr>,<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 1 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 1 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sr>,<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 2 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 2 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sr>,<VSa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 3 /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: error: undefined machine-specific constraint at this point: "Sa>" /home/dje/src/src/gcc/config/rs6000/vsx.md:1310: note: in operand 3 Thanks, David
