This bug is exposed on the ppc64le platform. The expression parser P3Build.bnf (and PHBuild.bnf) BuiltNot omitted to record the current token position on the quad stack. The patch changes all occurances of NEW to newBoolFrame to ensure that the tokenno recorded in the bool frame is set to a sensible value. BuildNot is fixed and improved to generate a virtual token recording the position of the subexpression. gcc/m2/ChangeLog: * gm2-compiler/M2LexBuf.mod (isSrcToken): Add block comment. Remove dead code. * gm2-compiler/M2Quads.def (BuildNot): Add notTokPos parameter. * gm2-compiler/M2Quads.mod (BuildNot): Add notTokPos parameter. Create and push virtual token. (PopBooltok): New procedure. (PushBooltok): New procedure. (PushBool): Re-implement using PushBooltok. (PopBool): Re-implement using PopBooltok. * gm2-compiler/P3Build.bnf (ConstFactor): Record token position of NOT. (Factor): Record token position of NOT. * gm2-compiler/PHBuild.bnf (ConstFactor): Record token position of NOT. (Relation): Push token position. (UnaryOrConstTerm): Push token position. (AddOperator): Push token position. (MulOperator): Push token position. Signed-off-by: Gaius Mulley <gaiusmod2@gmail.com>
