--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Gaius Mulley <ga...@gcc.gnu.org>: https://gcc.gnu.org/g:64b0130bb6702c67a13caefaae9facef23d6ac60 commit r14-8769-g64b0130bb6702c67a13caefaae9facef23d6ac60 Author: Gaius Mulley <gaiusm...@gmail.com> Date: Sat Feb 3 00:03:39 2024 +0000 PR modula2/113730 Unexpected handling of mixed-precision integer arithmetic This patch fixes a bug which occurs when an expression is created with a ZType and an integer or cardinal. The resulting subexpression is incorrecly given a ZType which allows compatibility with another integer/cardinal type. The solution was to fix the subexpression type. In turn this required a minor change to SArgs.mod. gcc/m2/ChangeLog: PR modula2/113730 * gm2-compiler/M2Base.mod (IsUserType): New procedure function. (MixTypes): Use IsUserType instead of IsType before calling MixTypes. * gm2-compiler/M2GenGCC.mod (GetTypeMode): Remove and import from SymbolTable. (CodeBinaryCheck): Replace call to MixTypes with MixTypesBinary. (CodeBinary): Replace call to MixTypes with MixTypesBinary. (CodeIfLess): Replace MixTypes with ComparisonMixTypes. (CodeIfGre): Replace MixTypes with ComparisonMixTypes. (CodeIfLessEqu): Replace MixTypes with ComparisonMixTypes. (CodeIfGreEqu): Replace MixTypes with ComparisonMixTypes. (CodeIfEqu): Replace MixTypes with ComparisonMixTypes. (CodeIfNotEqu): Replace MixTypes with ComparisonMixTypes. (ComparisonMixTypes): New procedure function. * gm2-compiler/M2Quads.mod (BuildEndFor): Replace GenQuadO with GenQuadOtok and pass tokenpos for the operands to the AddOp and XIndrOp. (CheckRangeIncDec): Check etype against NulSym and dtype for a pointer and set etype to Address. (BuildAddAdrFunction): New variable opa. Convert operand to an address and save result in opa. Replace GenQuad with GenQuadOtok. (BuildSubAdrFunction): New variable opa. Convert operand to an address and save result in opa. Replace GenQuad with GenQuadOtok. (BuildDiffAdrFunction): New variable opa. Convert operand to an address and save result in opa. Replace GenQuad with GenQuadOtok. (calculateMultipicand): Replace GenQuadO with GenQuadOtok. (ConvertToAddress): New procedure function. (BuildDynamicArray): Convert index to address before adding to the base. * gm2-compiler/SymbolTable.def (GetTypeMode): New procedure function. * gm2-compiler/SymbolTable.mod (GetTypeMode): New procedure function implemented (moved from M2GenGCC.mod). * gm2-libs/SArgs.mod (GetArg): Replace cast to PtrToChar with ADDRESS. gcc/testsuite/ChangeLog: PR modula2/113730 * gm2/extensions/fail/arith1.mod: New test. * gm2/extensions/fail/arith2.mod: New test. * gm2/extensions/fail/arith3.mod: New test. * gm2/extensions/fail/arith4.mod: New test. * gm2/extensions/fail/arithpromote.mod: New test. * gm2/extensions/fail/extensions-fail.exp: New test. * gm2/linking/fail/badimp.def: New test. * gm2/linking/fail/badimp.mod: New test. * gm2/linking/fail/linking-fail.exp: New test. * gm2/linking/fail/testbadimp.mod: New test.
