* symtable.insertvardata/insertconstdata added
* removed insert_in_data call from symtable.insert, it needs to be
called separatly. This allows to deref the address calculation
* procedures now calculate the parast addresses after the procedure
directives are parsed. This fixes the cdecl parast problem
* push_addr_param has an extra argument that specifies if cdecl is used
or not
on the endianess of the host operating system -> difficult to get
right. Use lo/hi(location.valueqword) instead (remember to use
valueqword and not value!!)
+ tprocessor enumeration moved to cpuinfo
+ linker in target_info is now a class
* many many updates for m68k (will soon start to compile)
- removed some ifdef or correct them for correct cpu
* asmsymbollist global is removed and moved into a new class
tasmlibrarydata that will hold the info of a .a file which
corresponds with a single module. Added librarydata to tmodule
to keep the library info stored for the module. In the future the
objectfiles will also be stored to the tasmlibrarydata class
* all getlabel/newasmsymbol and friends are moved to the new class
* foreach gets extra argument for passing local data to the
iterator function
* -CR checks also class typecasts at runtime by changing them
into as
* fixed compiler to cycle with the -CR option
* fixed stabs with elf writer, finally the global variables can
be watched
* removed a lot of routines from cga unit and replaced them by
calls to cgobj
* u32bit-s32bit updates for and,or,xor nodes. When one element is
u32bit then the other is typecasted also to u32bit without giving
a rangecheck warning/error.
* fixed pascal calling method with reversing also the high tree in
the parast, detected by tcalcst3 test
inlined from pexpr
* -an option that will write the secondpass nodes to the .s file, this
requires EXTDEBUG define to actually write the info
* fixed various internal errors and crashes due recent code changes
+ first parameter offset in stack now portable
* rename some constants
+ move some cpu stuff to other units
- remove unused constents
* fix stacksize for some targets
* fix generic size problems which depend now on EXTEND_SIZE constant
* removing frame pointer in routines is only available for : i386,m68k and vis targets
error was found
* generic changeregsize(reg,size) for i386 register resizing
* removed some more routines from cga unit
* fixed returnvalue handling
* fixed default stacksize of linux and go32v2, 8kb was a bit small :-)
+ some cleanup of unused types/variables
* move several constants from cpubase to their specific units
(where they are used)
+ att_Reg2str -> gas_reg2str
+ int_reg2str -> std_reg2str
* LOC_CONSTANT added for better constant handling
* secondadd splitted in multiple routines
* location_force_reg added for loading a location to a register
of a specified size
* secondassignment parses now first the right and then the left node
(this is compatible with Kylix). This saves a lot of push/pop especially
with string operations
* adapted some routines to use the new cg methods
* register allocation is now handled by a class and is mostly processor
independent (+rgobj.pas and i386/rgcpu.pas)
* temp allocation is now handled by a class (+tgobj.pas, -i386\tgcpu.pas)
* some small improvements and fixes to the optimizer
* some register allocation fixes
* some fpuvaroffset fixes in the unary minus node
* push/popusedregisters is now called rg.save/restoreusedregisters and
(for i386) uses temps instead of push/pop's when using -Op3 (that code is
also better optimizable)
* fixed and optimized register saving/restoring for new/dispose nodes
* LOC_FPU locations now also require their "register" field to be set to
R_ST, not R_ST0 (the latter is used for LOC_CFPUREGISTER locations only)
- list field removed of the tnode class because it's not used currently
and can cause hard-to-find bugs
instructions (e.g. "addl ref1,%eax" will be replaced by "addl %ebx,%eax"
if %ebx contains ref1). Previously only complete load sequences were
optimized away, but not such small accesses in other instructions than
mov/movzx/movsx
* fixed bug in n386add (introduced after compilerproc changes for string
operations) where calcregisters wasn't called for shortstring addnodes
* NOTE: from now on, the location of a binary node must now always be set
before you call calcregisters() for it
* fixed converting boolean to int64/qword
* fixed register allocation bugs which could cause internalerror 10
* isnode and asnode are completely processor indepent now as well
* fpc_do_as now returns its class argument (necessary to be able to use it
properly with compilerproc)
related things) to processor independent code (in new ncgflw unit)
+ generic cgobj unit which contains lots of code generator helpers with
global "cg" class instance variable
+ cgcpu unit for i386 (implements processor specific routines of the above
unit)
* updated cgbase and cpubase for the new code generator units
* include ncgflw unit in cpunode unit
early, caused bug reported by Aleksey V. Vaneev in mailing list on
2001/09/07 regarding 'problems with nested procedures and local vars'
("merged" from cga.pas in the fixes branch)
framepointer was being pushed on the stack, but this pushed framepointer
was never used nor removed from the stack again after the inlining was
done. It's now simply not pushed anymore, because the inlined procedure
can get the previous framepointer from the procedure in which it is being
inlined (merged)
* changed ninl and nadd to use these functions
* i386 set comparison functions now return their results in al instead
of in the flags so that they can be sued as compilerprocs
- removed all processor specific code from n386add.pas that has to do
with set handling, it's now all done in nadd.pas
* fixed fpc_set_contains_sets in genset.inc
* fpc_set_in_byte is now coded inline in n386set.pas and doesn't use a
helper anymore
* some small fixes in compproc.inc/set.inc regarding the declaration of
internal helper types (fpc_small_set and fpc_normal_set)
* changed the declaration of some set helpers somewhat to accomodate the
above change
* i386 still uses the old code for comparisons of sets, because its
helpers return the results in the flags
* dummy tc_normal_2_small_set type conversion because I need the original
resulttype of the set add nodes
NOTE: you have to start a cycle with 1.0.5!
* cgcal: deallocate hlper register only after call statement (fixes bug
with "procedure of object" and optimizer reported to bugrep on
2001/08/30) ('merged')
