Jonas Maebe
60dc4bf0a9 * moved call to "cleanup_regvars" to cga.pas for i386 because it has 
to insert "fstp %st0" instructions after the exit label
 2001-11-06 16:39:02 +00:00
peter
a059a1671d * fixed crash with inlining after aktprocdef change 2001-11-02 23:24:40 +00:00

    a temp
 2001-10-20 17:22:57 +00:00
Jonas Maebe
66567674ba + also replace mem references in modify operands with regs 2001-10-14 11:50:21 +00:00
Jonas Maebe
32deddeab1 * finetuned register allocation info for assignments 2001-10-14 11:49:51 +00:00
Jonas Maebe
82f7cf0957 + memory references are now replaced by register reads in "regular" 
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
 2001-10-12 13:58:05 +00:00
Jonas Maebe
97c1152c6d * finer granularity for allocation of reused/replaced registers 2001-10-12 13:55:03 +00:00
Jonas Maebe
eefd8e9f86 * fixed small crashing bug ("merged") 
* some more optimizations are now only done once at the end of the optimizing
    cycle instead of every iteration
 2001-10-12 13:53:24 +00:00
Jonas Maebe
8a2c142e46 * fixed internalerror(10) due to previous fpu overflow fixes ("merged") 
* 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
 2001-10-12 13:51:51 +00:00
Jonas Maebe
bdf2593265 * fixed range check errors 2001-10-04 14:33:28 +00:00

Jonas Maebe
f33d23922a - removed unnecessary i386 pass_2 of as- and isnode and added dummy generic ones 2001-09-30 16:12:46 +00:00
Jonas Maebe
170234049b - removed unused code (replaced by processor independent code) 2001-09-29 21:34:04 +00:00
Jonas Maebe
fc6d300a95 * almost all second pass typeconvnode helpers are now processor independent 
* 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)
 2001-09-29 21:32:46 +00:00
Jonas Maebe
fac1fb3d6c * fixed bug in a_load_reg_reg + implemented a_call 2001-09-29 21:32:19 +00:00
Jonas Maebe
b374bec6fb * changed all flow control structures (except for exception handling 
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
 2001-09-28 20:39:32 +00:00
Jonas Maebe
8e70f9aaf8 * fixed big bug in my previous changes (the arguent for bts/btr is always 
a 32 bit register, but it wasn't cleared properly if the value was only
    an 8 bit one)
 2001-09-28 20:38:51 +00:00
Jonas Maebe
49f399d750 * fixed bug reported by sg about self not being restored after calling 
setlength

 2001-09-19 11:04:41 +00:00
peter
45dab81414 * merged netbsd, fpu-overflow from fixes branch 2001-09-17 21:29:10 +00:00
Jonas Maebe
e8c8f8785a * fixed bug with assigning ansistrings (left^.location was released too 
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)
 2001-09-09 08:51:09 +00:00
Jonas Maebe
100a911290 * when calling an inline procedure inside a nested procedure, the 
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)
 2001-09-09 08:50:15 +00:00
Jonas Maebe
a39cd8a580 * made multiplying, dividing and mod'ing of int64 and qword processor 
independent with compilerprocs (+ small optimizations by using shift/and
    where possible)
 2001-09-05 15:22:09 +00:00
Jonas Maebe
17b2fa3424 * simplified det_resulttype code for include/exclude 
* include/exclude doesn't use any helpers anymore in the i386 secondpass
 2001-09-04 14:32:45 +00:00
Jonas Maebe
1fd6a2c5f8 * commented out some inactive code in csopt386 
+ small improvement: lea is now handled the same as mov/zx/sx
 2001-09-04 14:01:03 +00:00
Jonas Maebe
ed449defca + searchsystype() and searchsystype() functions in symtable 
* 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)
 2001-09-04 11:38:54 +00:00
Jonas Maebe
f256a47f04 * compilerproc implementation of set addition/substraction/... 
* 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!
 2001-09-03 13:27:41 +00:00

915b5cd7a9 * split constsym.value in valueord,valueordptr,valueptr. The valueordptr 
is used for holding target platform pointer values. As those can be
    bigger than the source platform.
 2001-09-02 21:18:28 +00:00
Jonas Maebe
8b3905de23 * i386*: call and jmp read their first operand 
* cgcal: deallocate hlper register only after call statement (fixes bug
    with "procedure of object" and optimizer reported to bugrep on
    2001/08/30) ('merged')
 2001-09-01 23:02:30 +00:00

2d610e9be3 * asbsd merged 2001-08-30 20:57:09 +00:00
peter
f88f6eb571 * rtti/init table updates 
* rttisym for reusable global rtti/init info
  * support published for interfaces
 2001-08-30 20:13:52 +00:00
Jonas Maebe
41a57028b9 * converted adding/comparing of strings to compileproc. Note that due 
to the way the shortstring helpers for i386 are written, they are
    still handled by the old code (reason: fpc_shortstr_compare returns
    results in the flags instead of in eax and fpc_shortstr_concat
    has wierd parameter conventions). The compilerproc stuff should work
    fine with the generic implementations though.
  * removed some nested comments warnings

fc704cd7b0 + Patch for wrong paramsize 2001-08-30 11:57:20 +00:00
Jonas Maebe
06f9cd4c96 * some fixes in compilerprocs for chararray to string conversions 
* conversion from string to chararray is now also done via compilerprocs
 2001-08-29 19:49:03 +00:00
Jonas Maebe
cecfe5dd49 * removed unused var 2001-08-29 17:50:45 +00:00
Jonas Maebe
003549eba1 * the optimizer now keeps track of flags register usage. This fixes some 
optimizer bugs with int64 calculations (because of the carry flag usage)
  * fixed another bug which caused wrong optimizations with complex
    array expressions
 2001-08-29 14:07:43 +00:00
Jonas Maebe
105b7ae809 + new createinternres() constructor for tcallnode to support setting a 
custom resulttype
  * compilerproc typeconversions now set the resulttype from the type
    conversion for the generated call node, because the resulttype of
    of the compilerproc helper isn't always exact (e.g. the ones that
    return shortstrings, actually return a shortstring[x], where x is
    specified by the typeconversion node)
  * ti386callnode.pass_2 now always uses resulttype instead of
    procsym.definition.rettype (so the custom resulttype, if any, is
    always used). Note that this "rettype" stuff is only for use with
    compilerprocs.
 2001-08-29 12:18:07 +00:00
Jonas Maebe
14576640c5 * fixed wrong regalloc info around FPC_MUL/DIV/MOD_INT64/QWORD calls 
* fixed partial result overwriting with the above calls too
 2001-08-29 12:03:23 +00:00
Jonas Maebe
e57f168475 + support for int64 LOC_REGISTERS in remove_non_regvars_from_loc 2001-08-29 12:01:47 +00:00
Jonas Maebe
fc92c3b336 + compilerproc implementation of most string-related type conversions 
- removed all code from the compiler which has been replaced by
    compilerproc implementations (using {$ifdef hascompilerproc} is not
    necessary in the compiler)
 2001-08-28 13:24:46 +00:00
florian
9746f4c2d6 * some cg reorganisation 
* some PPC updates
 2001-08-26 13:35:06 +00:00
Jonas Maebe
808ab9e7e7 * fixed big bug in handle_str that caused it to (almost) always call 
fpc_<stringtype>_longint
  * fixed small bug in handle_read_write that caused wrong warnigns about
    uninitialized vars with read(ln)
  + handle_val (processor independent val() handling)
 2001-08-24 12:33:54 +00:00
Jonas Maebe
460af7729c * fixed memory leak with coping of array-of-consts as valuepara 2001-08-24 12:22:14 +00:00
Jonas Maebe
a6cfe4083a + tempcreate/ref/delete nodes (allows the use of temps in the 
resulttype and first pass)
  * made handling of read(ln)/write(ln) processor independent
  * moved processor independent handling for str and reset/rewrite-typed
    from firstpass to resulttype pass
  * changed names of helpers in text.inc to be generic for use as
    compilerprocs + added "iocheck" directive for most of them
  * reading of ordinals is done by procedures instead of functions
    because otherwise FPC_IOCHECK overwrote the result before it could
    be stored elsewhere (range checking still works)
  * compilerprocs can now be used in the system unit before they are
    implemented
  * added note to errore.msg that booleans can't be read using read/readln
 2001-08-23 14:28:35 +00:00

    become longints, all constants >$7fffffff and <=cardinal($ffffffff)
    are cardinals and the rest are int64's.

    compiler and rtl

    after doing a 64bit rangecheck

Jonas Maebe
a4fde73649 + register renaming ("fixes" bug1088) 
* changed command line options meanings for optimizer:
      O2 now means peepholopts, CSE and register renaming in 1 pass
      O3 is the same, but repeated until no further optimizations are
        possible or until 5 passes have been done (to avoid endless loops)
  * changed aopt386 so it does this looping
  * added some procedures from csopt386 to the interface because they're
    used by rropt386 as well
  * some changes to csopt386 and daopt386 so that newly added instructions
    by the CSE get optimizer info (they were simply skipped previously),
    this fixes some bugs
