fpc/compiler/arm/armins.dat
Jonas Maebe d1538ab023 o added ARM VPFv2/VFPv3 support: 
+ 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.
