+ RTL support:
o VFP exceptions are disabled by default on Darwin,
because they cause kernel panics on iPhoneOS 2.2.1 at least
o all denormals are truncated to 0 on Darwin, because disabling
that also causes kernel panics on iPhoneOS 2.2.1 (probably
because otherwise denormals can also cause exceptions)
* set softfloat rounding mode correctly for non-wince/darwin/vfp
targets
+ compiler support: only half the number of single precision
registers is available due to limitations of the register
allocator
+ added a number of comments about why the stackframe on ARM is
set up the way it is by the compiler
+ added regtype and subregtype info to regsets, because they're
also used for VFP registers (+ support in assembler reader)
+ various generic support routines for dealing with floating point
values located in integer registers that have to be transferred to
mm registers (needed for VFP)
* renamed use_sse() to use_vectorfpu() and also use it for
ARM/vfp support
o only superficially tested for Linux (compiler compiled with -Cpvfpv6
-Cfvfpv2 works on a Cortex-A8, no testsuite run performed -- at least
the fpu exception handler still needs to be implemented), Darwin has
been tested more thoroughly
+ added ARMv6 cpu type and made it default for Darwin/ARM
+ ARMv6+ implementations of atomic operations using ldrex/strex
* don't use r9 on Darwin/ARM, as it's reserved under certain
circumstances (don't know yet which ones)
* changed C-test object files for ARM/Darwin to ARMv6 versions
* check in assembler reader that regsets are not empty, because
instructions with a regset operand have undefined behaviour in that
case
* fixed resultdef of tarmtypeconvnode.first_int_to_real in case of
int64->single type conversion
* fixed constant pool locations in case 64 bit constants are generated,
and/or when vfp instructions with limited reach are present
WARNING: when using VFP on an ARMv6 or later cpu, you *must* compile all
code with -Cparmv6 (or higher), or you will get crashes. The reason is
that storing/restoring multiple VFP registers must happen using
different instructions on pre/post-ARMv6.
