for all non-ppc(32/64) Darwin platforms
o pass the macosx-version-min/iphoneos-version-min to clang as an assembler,
so that it properly sets this information starting with Xcode 7 (solves
errors when targeting the iOS simulator, and warnings about object files
being compiled for a different OS X version when targeting (Mac) OS X)
o the old assembler is still selectable via -Aas-darwin (required with
Xcode 3.1.x and older)
o since the first Xcode version that shipped with Clang is Xcode 3.2, which
is available for Mac OS X 10.6, most users should not encounter any issues
with the new default (in fact, it fixes some tests for x86 because Clang
supports some instructions that "as" doesn't). Clang does not support
Stabs however, so -gs does require the use of -Aas-darwin

GNU as from binutils for Darwin, and Apple's "as" is based on an old
version of GNU as)
o this will not cause any backward compatibility problems, as the
previous identifier for as_darwin was "AS-Darwin" and the compiler
compared the uppercase value of the -A parameter to the identifier,
so it was not explicitly selectable earlier. The new name is "AS",
so it is explicitly selectable via -Aas like on other platforms.

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
git-svn-id: trunk@31628 -
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.
git-svn-id: branches/laksen/armiw@29277 -
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.
git-svn-id: branches/laksen/armiw@29247 -
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.
git-svn-id: trunk@21685 -
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 $)
