RRX (Rotate Right with eXtend) does a single bit right rotation through
the carry. So it does not take any arguments, neither constant nor
register.
Also remove redundant shiftmode2str and replace usage of it with gas_shiftmode2str.

of the AVR-specific ifdef'ed variant
o since the only special character we use in mangled names on all platforms
is $, added a new field to tasminfo called "dollarsign" that holds the
character $'s should be replaced with (if it doesn't have to be replaced,
leave it at $)

o new eabihf (hard float) abi
o vfpv3_d16 variant of VFP (default variant used by EABI assemblers: VFPv3
with only 16 double registers instead of 32) and pass it to GNU as
o make the odd numbered single precision floating point VFP registers
available for explicit allocation for use by the calling convention
* fixed copy/paste error in stdname of S30 register
-> use -dFPC_ARMHF to create an ARM eabi hard float compiler
(mantis #21554)
git-svn-id: trunk@20660 -
* generate add.w instead of add for thumb-2 in case one of the registers
is > r8
* add register interferences for the "add" instruction so the register
allocator can detect invalid instruction forms (even for assembler code)
* fixed error in thumb2.inc detected by the previous change

the opposite meaning, af_stabs_use_function_absolute_addresses), because it
is different on Darwin for the internal and external assembler)

+ 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.

method in TArmGNUAssembler, because it's cleaner (no ifdef) and it
mustn't be added for darwin (which uses TArmAppleGNUAssembler)

- invalid calling conventions for a certain cpu are rejected
- arm softfloat calling conventions
- -Sp for cpu dependend code generation
- several arm fixes
- remaining code for value open array paras on heap
