+ A few small changes that speed up the peephole optimizer.
+
+ * src/SDCCpeeph.c
+
+2003-08-22 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Try to make the peephole optimizer smarter by maintaining
+ an association between the assembly source code and the
+ iCodes that originated them. Put this information to use
+ with a new peephole rule condition "notVolatile" so that
+ the rules can be aggressive yet still safe.

+ Fixed bug #741761
+
+ * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

+
+2003-08-20 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Changed the type of the result of the ! (NOT) operator to char;
+ previously it returned the same type as the source. This allows
+ us to eliminate all the genFloatNot functions (all of its target
+ implementations were very buggy) since !float can use the same
+ code as !long now.
+
+ * src/SDCCicode.c (ast2iCode): ! returns char

+ pic patch provided by Slade Rich <slade_rich@yahoo.com>
+ 1. Interrupt would not compile properly. Ensure PCLATH register is saved
+ during interrupts. Ensure WSAVE is located at a shared bank address.
+ 2. Fixed page selection in some places
+ 3. Fixed BTFSS/C to where necessary use registers directly and not simply
+ the registers name strings.
+ 4. Fixed "signed / unsigned compare" compiler warnings.
+ 5. The PIC port manages its own allocation of the general purpose
+ registers, but makes no attempt to reuse them. As a result when
+ compiling it soon runs out of general purpose registers. Some
+ additional code was added to the files pcode.c and device.c to walk
+ through the function call tree and rename the registers so that they
+ get reused.

+
+2003-08-18 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ 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.

+2003-08-17 Frieder Ferlemann <Frieder.Ferlemann@web.de>
+
+ 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).

+ 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/regression/tests/bitfields.c: tests added
+
+2003-08-13 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ 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.
