multiplying. - (ffecom_transform_equiv_): Ditto. - - Fix 970712-3.f: - * stb.c (ffestb_R10014_): Fix flaky fall-through in error - test for FFELEX_typeCONCAT by just replicating the code, - and do FFELEX_typeCOLONCOLON while at it. -

transforming a dummy argument, to avoid a crash. - * ste.c (ffeste_R1227): Don't return a value if the - result decl, or its type, is error_mark_node. - - Fix 970626-4.f: - * lex.c (ffelex_splice_tokens): `-fdollar-ok' is -

Not as complete a check as looking through the - entire symbol table (which does matter, since some - code in equiv.c used to remove symbols from the lists - for an ffeequiv victim but not remove that victim as the - symbol's equiv info), but this check did find some - real bugs in the code (that were fixed). - -Mon Feb 24 16:42:13 1997 Craig Burley <burley@gnu.ai.mit.edu> - - * com.c (ffecom_expr_intrinsic_): Fix a couple of - warnings about uninitialized variables. - * intrin.c (ffeintrin_check_): Ditto, but there were - a couple of _real_ uninitialized-variable _bugs_ here! - (ffeintrin_fulfill_specific): Ditto, no real bug here. - -Sun Feb 23 15:01:20 1997 Craig Burley <burley@gnu.ai.mit.edu> - - Clean up diagnostics (especially about intrinsics): - * bad.def (FFEBAD_UNIMPL_STMT): Remove. - (FFEBAD_INTRINSIC_*, FFEBAD_NEED_INTRINSIC): Clean these - up so they're friendlier. - (FFEBAD_INTRINSIC_CMPAMBIG): New. - * intrin.c (ffeintrin_fulfill_generic, - ffeintrin_fulfill_specific, ffeintrin_is_intrinsic): - Always choose - generic or specific name text (which is for doc purposes - anyway) over implementation name text (which is for - internal use). - * intrin.def: Use more descriptive name texts for generics - and specifics in cases where the names themselves are not - enough (e.g. IDATE, which has two forms). - - Fix some intrinsic mappings: - * intrin.def (FFEINTRIN_specIDINT, FFEINTRIN_specAND, - FFEINTRIN_specDFLOAT, FFEINTRIN_specDREAL, FFEINTRIN_specOR, - FFEINTRIN_specXOR): Now have their own implementations, - instead of borrowing from others. - (FFEINTRIN_specAJMAX0, FFEINTRIN_specAJMIN0, FFEINTRIN_specBJTEST, - FFEINTRIN_specDFLOTJ, FFEINTRIN_specFLOATJ, FFEINTRIN_specJIABS, - FFEINTRIN_specJIAND, FFEINTRIN_specJIBCLR, FFEINTRIN_specJIBITS, - FFEINTRIN_specJIBSET, FFEINTRIN_specJIDIM, FFEINTRIN_specJIDINT, - FFEINTRIN_specJIDNNT, FFEINTRIN_specJIEOR, FFEINTRIN_specJIFIX, - FFEINTRIN_specJINT, FFEINTRIN_specJIOR, FFEINTRIN_specJISHFT, - FFEINTRIN_specJISHFTC, FFEINTRIN_specJISIN, FFEINTRIN_specJMAX0, - FFEINTRIN_specJMAX1, FFEINTRIN_specJMIN0, FFEINTRIN_specJMIN1, - FFEINTRIN_specJMOD, FFEINTRIN_specJNINT, FFEINTRIN_specJNOT,): - Turn these implementations off, since it's not clear - just what types they expect in the context of portable Fortran. - (DFLOAT): Now in FVZ family, since f2c supports them - - Support intrinsic inquiry functions (BIT_SIZE, LEN): - * intrin.c: Allow `i' in <arg_extra>. - * intrin.def (FFEINTRIN_impBIT_SIZE, FFEINTRIN_impLEN): - Mark args with `i'. - -Sat Feb 22 13:34:09 1997 Craig Burley <burley@gnu.ai.mit.edu> - - Only warn, don't error, for reference to unimplemented - intrinsic: - * bad.def (FFEBAD_INTRINSIC_UNIMPLW): Warning version - of _UNIMPL. - * intrin.c (ffeintrin_is_intrinsic): Use new warning - version of _UNIMPL (FFEBAD_INTRINSIC_UNIMPLW). - - Complain about REAL(Z) and AIMAG(Z) (Z is DOUBLE COMPLEX): - * bad.def (FFEBAD_INTRINSIC_CMPAMBIG): New diagnostic. - * expr.c: Needed #include "intrin.h" anyway. - (ffeexpr_token_intrincheck_): New function handles delayed - diagnostic for "REAL(REAL(expr)" if next token isn't ")". - (ffeexpr_token_arguments_): Do most of the actual checking here. - * intrin.h, intrin.c (ffeintrin_fulfill_specific): New - argument, check_intrin, to tell caller that intrin is REAL(Z) - or AIMAG(Z). All callers updated, mostly to pass NULL in - for this. - (ffeintrin_check_): Also has new arg check_intrin for same - purpose. All callers updated the same way. - * intrin.def (FFEINTRIN_impAIMAG): Change return type - from "R0" to "RC", to accommodate f2c (and perhaps other - non-F90 F77 compilers). - * top.h, top.c: New option -fugly-complex. - - New GNU intrinsics REALPART, IMAGPART, and COMPLEX: - * com.c (ffecom_expr_intrinsic_): Implement impCOMPLEX - and impREALPART here. (specIMAGPART => specAIMAG.) - * intrin.def: Add the intrinsics here. - - Rename implementations of VXTIDATE and VXTTIME to IDATEVXT - and TIMEVXT, so they sort more consistently: - * com.c (ffecom_expr_intrinsic_): - * intrin.def: - - Delete intrinsic group `dcp', add `gnu', etc.: - * intrin.c (ffeintrin_state_family): FFEINTRIN_familyGNU - replaces FFEINTRIN_familyDCP, and gets state from `gnu' - group. - Get rid of FFEINTRIN_familyF2Z, nobody needs it. - Move FFEINTRIN_specDCMPLX from DCP family to FVZ family, - as f2c has it. - Move FFEINTRIN_specDFLOAT from F2C family to FVZ family. - (FFEINTRIN_specZABS, FFEINTRIN_specZCOS, FFEINTRIN_specZEXP, - FFEINTRIN_specZLOG, FFEINTRIN_specZSIN, FFEINTRIN_specZSQRT): - Move these from F2Z family to F2C family. - * intrin.h (FFEINTRIN_familyF2Z, FFEINTRIN_familyDCP): Remove. - (FFEINTRIN_familyGNU): Add. - * top.h, top.c: Replace `dcp' with `gnu'. - - * com.c (ffecom_expr_intrinsic_): Clean up by collecting - simple conversions into one nice, conceptual place. - Fix up some intrinsic subroutines (MVBITS, KILL, UMASK) to - properly push and pop call temps, to avoid wasting temp - registers. - - * g77.c (doit): Toon says variables should be defined - before being referenced. Spoilsport. - - * intrin.c (ffeintrin_check_): Now Dave's worried about - warnings about uninitialized variables. Okay, so for - basic return values 'g' and 's', they _were_ - uninitialized -- is determinism really _that_ useful? - - * intrin.def (FFEINTRIN_impFGETC): Fix STATUS argument - so that it is INTENT(OUT) instead of INTENT(IN). - -1997-02-21 Dave Love <d.love@dl.ac.uk> - - * intrin.def, com.c: Support Sun-type `short' and `long' - intrinsics.
