c2fe8dbd99 * merged macos entry/exit code generation into the general one. 2003-08-08 15:49:24 +00:00
Jonas Maebe
a3cb0d2002 * don't use rg.getregisterint() anymore in g_stackframe_entry_*, because 
the register colouring has already occurred then, use a hard-coded
    register instead
 2003-07-23 11:02:23 +00:00
Jonas Maebe
356ee447ba * "lastsaveintreg" is RS_R31 instead of RS_R27 with -dnewra, because 
there are no scratch regs anymore

5ab3ea0af5 - disabled some debugging code 2003-07-23 10:58:06 +00:00
Jonas Maebe
d73acd12f6 * fixed newra bug due to the fact that we sometimes need a temp reg 
when loading/storing to memory (base+index+offset is not possible)
    and because a reference is often freed before it is last used, this
    temp register was soemtimes the same as one of the reference regs

Jonas Maebe
2763f461ce * VOLATILE_REGISTERS was wrong (it was more or less the inverted set 
of what it had to be :/ )
 2003-07-06 15:28:24 +00:00
Jonas Maebe
cc6a8fbe91 * make sure all registers except r0 are handled by the register 
allocator for -dnewra
 2003-07-06 15:27:44 +00:00

marco
152b525419 * committed fix that swaps int64 parameters hi and lo. 2003-05-30 22:35:03 +00:00

 2003-05-30 18:52:10 +00:00
Jonas Maebe
d321606bc5 * changed scratchregs from r28-r30 to r29-r31

of an addnode when using regvars
 2003-05-30 18:49:14 +00:00
Jonas Maebe
c70f75f1b7 * compile with -dppc603 to not use unaligned float loads in move() and 
g_concatcopy, because the 603 and 604 take an exception for those
    (and netbsd doesn't even handle those in the kernel). There are
    still some of those left that could cause problems though (e.g.
    in the set helpers)
 2003-05-29 21:17:27 +00:00
Jonas Maebe

df5e0bbfc6 * fsqrt is an optional instruction in the ppc architecture and isn't 
implemented by any current ppc afaik, so use the generic sqrt routine
    instead (adapted so it works with compilerproc)
 2003-05-24 13:39:32 +00:00
Jonas Maebe
ee71991a7f * don't save callee-save registers in the caller as well (the ppc code

a place in the link area reserved for compiler use.
 2003-05-24 11:47:27 +00:00
Jonas Maebe
74301b9544 * fixed support for nested procedures and more parameters than those

    nested procedure from a deeper nested procedure)
 2003-05-23 18:51:26 +00:00

Jonas Maebe
56132c1a9c * assembler procedures now again get a stackframe if they have local

offset seems now to be calculated correctly and a lot of duplicate
