c1e4ee94be Fix kernel profiling on HPPA.
- stop gcc emitting stuff that HPUX requires
- don't use splhigh() in MCOUNT_ENTER as a call to _mcount will be
  generated at the moment. Disable interrupts in hardware instead.
- Fix _PROF_PROLOGUE to save/restore all the register args when calling
  _mcount.
- Fixup LEAF_ENTRY to dtrt (I think) in the GPROF case.
- Provide LEAF_ENTRY_NOPROFILE and sprinkle its use where i) profiling
  causes problems, e.g. trap handlers, and ii) where it just doesn't
  make sense, e.g. start.

20237a6fdb Commit autoconf-generated file after modifying configure.ac to allow
override of the TARGET_LIBC_PROVIDES_SSP test.
2007-06-07 08:59:53 +00:00
he
bd8f620dfb Modify the gcc configure script to allow override of the "target libc
has ssp functions built-in" test via the TARGET_LIBC_PROVIDES_SSP environment
variable, to allow us to configure a cross-compiler appropriately without
having to try to find out by looking in the target's source directory.

Tweak our build to tell gcc that the ssp bits are now in libc.

The native compiler appears to already think that the ssp bits
live in libc, so no change appears to be needed there.

The autoconf-generated configure script will be committed separately shortly.

dec8719ee4 For nonimmediate operands of SImode, don't use "g" anymore, use "nrmT" instead.
"g" matches just about anything including SYMBOL_REF, CONST, LABEL_REF which
should not be operands for most instructions in PIC mode.  (movsi can handle
then and addsi3 can handle them in a few limited cases).

58ad121651 Step 1 of getting gcc to generate VAX PIC code again. These steps are being
committed in "smallish" steps.  This step incorporates the switch to MEM_P,
REG_P, and CONST_INT_P.  Use bool/true/false where appropriate.  PRINT_OPERAND
moves from being a large macro in vax.h print_operand in vax.c.  Fix rtx cost
for a constant of 0.  This eliminates unneeded moves when setting to 0 would
be fine.

Lastly, include completely new (on by default) code for DImode move, addition,
and subtract.  This code is significantly faster and smaller that what existed
before.

There still seem to be codegen bugs, however.
