Fixed a bunch of instruction encodings by comparing bulks of handwritten tests to binutils assembled versions.
Fixed emission of regsets of S and D registers above 15.
Fixed assembler reader for RRX shiftmode.
There can be a size postfix after a condition code in UAL assembler syntax. This has been added to the assembler reader.

Switched codegeneration of VFPv2 and VFPv3 to use UAL mnemonics and syntax.
Updated VFP code in RTL to use UAL syntax too.
Added preliminary ELF support for ARM.
Added support for linking of WinCE COFF files. Should work for with a standard ARMv4-I target.

Updated boot code for all Cortex-M3 controllers, and sc32442b to use weak linking for exception tables.
Cortex-M3 devices now also share initialization routine to simplify maintenance
STM32F10x classes now have specific units which fit the interrupt source names and counts

and add usermode parsing of LDM/STM ops
This patch basically extends the ARM assembly reader a bit to properly parse CPSR and
SPSR flags for the MSR opcode, and allows the reader to understand
the ^ modifer for register lists for STMxx and LDMxx.
Previously the following combinations weren't possible in straight assembler:
MRS R0, CPSR
MRS R0, SPSR
MSR CPSR_CX, R0
LDMIA SP, {R0-R15}^
etc..

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.

- invalid calling conventions for a certain cpu are rejected
- arm softfloat calling conventions
- -Sp for cpu dependend code generation
- several arm fixes
