                   1256: 
                   1257:        * output-sparc.c (various places): changed dispatches on SYMBOL_REF
                   1258:        to dispatches on CONSTANT_ADDRESS_P since we now recognize any CONST

                   1268:        * stmt.c (expand_function_start): functions which are nested use
                   1269:        DECL_CONTEXT.  For these functions, test that their DECL_CONTEXT is
                   1270:        a LET_STMT node.

                   1281:        declarating, not defining.  Change types to error_mark_node
                   1282:        in both the PARM_DECL and the list of types.
                   1283: 
                   1284:        * dbxout.c (dbxout_type): It's not a bug if a RECORD_TYPE
                   1285:        has a typedef as its TYPE_NAME.  That happens in C++.
                   1286: 
                   1287:        * Make each `asm' with operands record its source file/line
                   1288:        with reg-notes.  It doesn't work to emit a special note before the insn
                   1289:        because the insn can be moved by loop_optimize.
                   1290:        * stmt.c (expand_asm_operands): New args FILENAME, LINE.
                   1291:        Record them in the insn, in reg notes.

                   1297: 
                   1298:        * reload.c (find_reloads): Don't clear BADOP for a reg letter

                   1301:        * reload.c (find_reloads): If an `asm' insn gets an error,
                   1302:        change it to a USE to avoid duplicate error msgs or later trouble.
                   1303: 
                   1304:        * reload.c (find_reloads_address): Reloading a constant address,
                   1305:        specify Pmode as the mode for push_reloads, in case of CONST_INT.
                   1306: 
                   1307:        * expr.c (emit_push_insn): Fix calc. of space needed when PARTIAL > 0.
                   1308:        Both scalar case and BLKmode case needed fixing.
                   1309: 
                   1310:        * sparc.md (load/store constant address):
                   1311:        Moving DF from mem to cpu regs, don't go via %f0.
                   1312:        Don't use std/ltd if alignment is wrong or uncertain.

                   1318: 
                   1319:        * sparc.md: remove patterns which generate annulled branch insns.
                   1320:        They are correct, but those insns confuse GDB.
                   1321: 
                   1322:        * tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS):
                   1323:        Treat any constant address like a SYMBOL_REF.
                   1324:        * sparc.md: Check for CONSTANT_ADDRESS_P rather than SYMBOL_REF.
                   1325: 
                   1326:        * sparc.md: Peepholes now accept SYMBOL_REF addresses.

                   1343:        * tree.h (DECL_FIELD_CONTEXT): new macro.  Points to the type that a
                   1344:        FIELD_DECL is a member of.  For C, this is just DECL_CONTEXT.
                   1345: 
                   1346:        * tree.c (build_method_type): typo used "==" to assign basetype to

                   1382:        method, not the FUNCTION_TYPE from which the METHOD_TYPE is derived.
                   1383:        
                   1384:        * Makefile: Changed target of BINDIR from /usr/local to

                   1392:        (NOTICE_UPDATE_CC): Test SET_SRC, not SET_DEST, for a CALL rtx.
                   1393:        (PRINT_OPERAND): New code-letter `m' says output operand as an address.

                   3976:        This can cause the use of multiple insns with same output reg,
                   3977:        which can confuse cse.

                   3983:        (scan_loop): If consec_sets_invariant_p returns 2, set m->cond.

                   3996:        came in regs, pretend it came on stack.
                   3997:        Handle pretending a BLKmode var came on the stack.
                   3998:        If REG_PARM_STACK_SLOT, count stack space for each parm
                   3999:        even if the parm came in a register; and use that stack space
                   4000:        if the parm needs to be addressable or is BLKmode.
                   4001:        Rearrange to simplify conditionals.
                   4002:

                   4004: 
                   4005:        * local-alloc.c:
                   4006:        `qty_...' vectors' elements for hard-reg-numbers now aren't used.
                   4007:        `reg_qty' elements for hard-reg numbers now aren't used,
                   4008:        and the element for a pseudo is never a hard-reg number.
                   4009:        (local_alloc): No need to reset those elements.
                   4010:        No need to reset elements out of range of prev block's NEXT_QTY.
                   4011:        (reg_is_born, reg_is_set, wipe_dead_reg):
                   4012:        Divide labor in same way for hard regs and pseudos;
                   4013:        simplify using fact that locality-to-basic-block has been precomputed
                   4014:        and recorded in reg_qty; avoid refs to reg_qty[HARDREG].
                   4015:        (reg_is_born, wipe_dead_regs): Block-number arg no longer needed.
                   4016: 
                   4017:        * local-alloc.c (combine_regs): Remove old code for tying hard regs
                   4018:        to pseudos; great simplification results.
                   4019:        Use find_regno_note, not regno_dead_p.

                   4021: Wed Jun  8 00:18:04 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
                   4022: 
                   4023:        * reload.c (subst_reg_equivs): Set a flag if anything is changed.
                   4024:        (find_reloads_address): Check that flag to avoid extra work.
                   4025:        Also check early for safe reg+const address and avoid work.

                   4035:        Inhibition was needed when the SET_SRC was the only place to find the
                   4036:        equivalent value; now it is in the REG_EQUIV note.
                   4037: 
                   4038:        * stmt.c (expand_asm_operands): If NINPUTS is 0, make vec of no elts.

                   4061:        * cse.c (cse_insn): Speedup: instead of safe_hash, use canon_hash

                   4071:        * flow.c (life_analysis): Don't call volatile_refs_p for a CALL_INSN;

                   4073:        (propagate_block): Don't call mark_{used,set}_regs for a stack-pop
                   4074:        since if it isn't dead it has no effect on any useful life data.
                   4075:        (mark_set_1): Return quickly if setting stack-ptr, and almost as
                   4076:        quickly if setting any hard reg.
                   4077:        (mark_used_regs): Likewise for refs.

                   4082:        in integer case (they were for casting a pointer).
                   4083: 
                   4084:        * parse.y (compstmt_or_error): Parse a compstmt after ignoring error.
                   4085:        Use this for fctn body so that an error after store_parm_decls

                   4087:        Typical cause was missing semi at end of last parmdecl.
