* tregisteralloctor renamed to trgobj
* removed rgobj from a lot of units
* moved location_* and reference_* to cgobj
* first things for mmx register allocation
* fixed some volatile register bugs
+ -dnotranslation option for -dnewra, which causes the registers not to
be translated from virtual to normal registers. Requires support in
the assembler writer as well, which is only implemented in aggas/
agppcgas currently
* ppc get/freeintparaloc now check whether the parameter regs are
properly allocated/deallocated (and get an extra list para)
* ppc a_call_* now internalerrors if pi_do_call is not yet set
* fixed lot of missing pi_do_call's
* procinfo renamed to current_procinfo
* procinfo will now be stored in current_module so it can be
cleaned up properly
* gen_main_procsym changed to create_main_proc and release_main_proc
to also generate a tprocinfo structure
* fixed unit implicit initfinal
a new procdef declaration
* aktprocsym removed
* lexlevel removed, use symtable.symtablelevel instead
* implicit init/final code uses the normal genentry/genexit
* funcret state checking updated for new funcret handling
and aliases for result and function name are added using absolutesym
* vs_hidden parameter for funcret passed in parameter
* vs_hidden fixes
* writenode changed to printnode and released from extdebug
* -vp option added to generate a tree.log with the nodetree
* nicer printnode for statements, callnode
variables. No space is reserved for a function result however.
Also, the register parameters aren't automatically saved on the stack
anymore in assembler procedures.
offset seems now to be calculated correctly and a lot of duplicate
calculations have been removed. Nested functions accessing the parent's
function result don't work at all though :(
+ getregisterint will return imaginary registers with $newra
+ -sr switch added, will skip register allocation so you can see
the direct output of the code generator before register allocation
- -V option for generating bug report tracing
- more tracing for option parsing
- errors for cdecl and high()
- win32 import stabs
- win32 records<=8 are returned in eax:edx (turned off by default)
- heaptrc update
- more info for temp management in .s file with EXTDEBUG
* 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
+ ret_in_reg to replace ret_in_acc
(fix some register allocation bugs at the same time)
+ save_std_register now has an extra parameter which is the
usedinproc registers
* 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
* The whilen and repeatn are now completely unified into whilerepeatn. This
allows the state tracker to change while nodes automatically into
repeat nodes.
* Resulttypepass improvements to the notn. 'not not a' is optimized away and
'not(a>b)' is optimized into 'a<=b'.
* Resulttypepass improvements to the whilerepeatn. 'while not a' is optimized
by removing the notn and later switchting the true and falselabels. The
same is done with 'repeat until not a'.
* 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
+ 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
in most cases and not written to the ppu
* add mangeledname_prefix() routine to generate the prefix of
manglednames depending on the current procedure, object and module
* removed static procprefix since the mangledname is now build only
on demand from tprocdef.mangledname
* 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
* writing of procvar headers is more complete (mention var/const/out for
paras, add "of object" if applicable)
+ error if declaring explicit self para as var/const
* fixed mangled name of procedures which contain an explicit self para
* parsing para's should be slightly faster because mangled name of
procedure is only updated once instead of after parsing each para
(all merged from fixes)
