    directives are parsed. This fixes the cdecl parast problem
  * push_addr_param has an extra argument that specifies if cdecl is used
    or not

3ab3c91e0a - remove valuelow/valuehigh fields from tlocation, because they depend 
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!!)

Jonas Maebe
807cf0000b * fixed regvar-related bugs (the load node set the location to 
LOC_REGISTER instead of LOC_CREGISTER and the assignment node didn't
    support loading constants in LOC_CREGISTER's)
 2002-04-03 10:43:37 +00:00

peter
5b242f7741 * tlocation,treference update 
* 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
 2002-04-02 17:11:27 +00:00
Jonas Maebe

Jonas Maebe
7fb55bf4e4 + a_loadfpu_* and a_loadmm_* methods in tcg 
* 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

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
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

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

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

 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
peter
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

    with "procedure of object" and optimizer reported to bugrep on
    2001/08/30) ('merged')
 2001-09-01 23:02:30 +00:00

  * 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

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

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

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
