3056a64bf0 * fixed regvars support. Needs -doldregvars to activate. Only tested with 
ppc, other processors should however only require maxregvars and
    maxfpuregvars constants in cpubase.pas. Remember to take scratch-
    registers into account when defining that value.

6b83738e7d + generic implementation of tcg.g_flags2ref() 
* tcg.flags2xxx() now also needs a size parameter
 2002-07-27 19:53:51 +00:00
florian
59abf2555b * types.pas renamed to defbase.pas because D6 contains a types 
unit so this would conflicts if D6 programms are compiled
  + Willamette/SSE2 instructions to assembler added

4dcd96747e * moved entry and exitcode to ncgutil and cgobj 
* 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
 2002-05-12 16:53:04 +00:00

the optimizer

59f8a16c39 + a_jmp_cond -> a_jmp_always (a_jmp_cond is NOT portable) 
+ changeregsize -> rg.makeregsize
 2002-04-21 15:24:38 +00:00
carl
87aa88e9b7 + generic FPC_CHECKPOINTER 
+ 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
 2002-04-20 21:32:23 +00:00
peter
3bcfe33002 * fixed stackcheck that would be called recursively when a stack 
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 :-)

5e7a1e3729 * removed unused units 
* use tlocation.size in cg.a_*loc*() routines
 2002-04-04 19:05:54 +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
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

b4cc4b7b01 * removed compiler warnings 2002-03-04 19:10:11 +00:00
Jonas Maebe
f15dbd7bf0 * range checking is now processor independent (part in cgobj, part in cg64f32) and should work correctly again (it needed some changes after the changes of the low and high of tordef's to int64) * maketojumpbool() is now processor independent (in ncgutil) * getregister32 is now called getregisterint 2001-12-30 17:24:45 +00:00
Jonas Maebe
91f567bb66 * powerpc/cgcpu.pas compiles :) 
* several powerpc-related fixes

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
