vs_written, vs_readwritten. vs_initialised is the old vs_assigned;
vs_used has been replaced by vs_read, vs_written and vs_readwritten
* the valid_for_*() routines in htypechk now get an extra parameter to
decide whether or not errors should be reported
git-svn-id: trunk@1913 -
* 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
* Fixed registers that are allocated but not freed in several nodes
* Tweak to register allocator to cause less spills
* 8-bit registers now interfere with esi,edi and ebp
Compiler can now compile rtl successfully when using new register
allocator
* fixed inlining of write()
* switched statementnode left and right parts so the statements are
processed in the correct order when getcopy is used. This is
required for tempnodes
* Moved pocall_internconst to po_internconst because it is not a
calling type at all and it conflicted when inlining of these small
functions was requested
* 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
* 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
* 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
+ nopt.pas, nadd.pas, i386/n386opt.pas: optimized nodes for adding strings
and constant strings/chars together
* n386add.pas: don't copy temp strings (of size 256) to another temp string
when adding
