+
+ Made bitfield a distinct type from bit so that bitfields
+ convert as per ANSI C and bits retain their traditional
+ boolean style behaviour. Implemented bitfield support in
+ the z80 port.

+ * src/SDCCsymt.c,
+ * src/SDCCast.c,
+ * src/cdbFile.c,
+ * src/mcs51/gen.c,
+ * src/ds390/gen.c: bit v bitfield split
+ * src/z80/gen.c: New support for bitfields
+ * support/regression/tests/bitfields.c: reenabled z80,
+ added more tests

+
+ Rules 246.x, 247.x relate to bitfields, the others speed up
+ access to xdata mapped I/O devices.
+
+ * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
+
+2003-08-16 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Cleaned up genPackBits and genUnpackBits and added two helper
+ functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
+ for literal assignments in genPackBits (thanks to Frieder for
+ reminding me).

+2003-08-16 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Fixed bug #748310 (pointer to function type mishandled when the
+ function name is omitted). Also fixed a SIGSEGV when a function
+ attribute (reentrant, etc) is used on a non-function or on a
+ function but misplaced before the parameter list.
+
+ * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
+ bug #748310
+ * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
+ * support/Util/SDCCerr.h,
+ * support/Util/SDCCerr.c: Added func attr misuse error msg
+
+2003-08-13 Bernhard Held <bernhard@bernhardheld.de>
+
+ Fixed bug #787649 by anonymous
+ * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
+ * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
+
+2003-08-14 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Fixed numerous bitfield problems.
+
+ * src/SDCC.y: More bitfield related error checking
+ * src/SDCCsymt.h,
+ * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
+ * support/Util/SDCCerr.h,
+ * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
+ * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
+ * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
+ * support/regression/tests/bitfields.c: tests added
+

+
+ Made the constant following the "interrupt" keyword optional. If
+ omitted, the function will not automatically be given an entry
+ in the interrupt vector table (similar to #pragma NOIV, but
+ less syntacticly kludgy). The interrupt number is also now
+ range checked. Also fixed a bug in the high order bit example
+ in the manual.

+
+ * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
+ * src/SDCCicode.c (operandOperation): rewritten some ops
+ (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
+ * src/SDCCsymt.c (computeType): literals are handled the same way as any
+ other type
+ * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
+ be re-activated by defining REDUCE_LITERALS)
+ * src/SDCCval.c (constVal): fixed; hex and octal constants can be
+ unsigned, but are signed by default
+ * src/SDCCval.c (constVal): rearranged
+ * src/SDCCval.c (valMod): preliminary fix
+ * src/SDCCval.c (valCastLiteral): use TYPE_* types
+ * support/regression/literalop.c: added, work in progress
