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

and above, so this also works when calling thumb code (should actually
also be done for ARMv5T, but we don't have a monicker for that yet)
* use BX instead of "mov r15, r14" for simple returns from subroutines
on ARMv6+ to support returning to thumb code from ARM code (idem)
git-svn-id: trunk@14332 -
+ 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.

* the objc unit links against the Foundation instead of against the Cocoa
framework, and inludes an interface to either the fragile or non-fragile
obj-c run time depending on the target platform
+ support for the non-fragile Objective-C runtime/ABI, as used on Mac OS X
for ARM (iPhone) 64 bit (PowerPC/64, x86_64) -- all these targets now
are now also supported for the objectivec1 modeswitch
+ support for private_extern symbol bindings, required for the above
* mark objcclasses that are declared in the implementation section of a
unit as "hidden" (not sure what the effect is, since the Objective-C
runtime does not seem to do anything with this flag)
* enabled all obj-c tests for the newly supported platforms
git-svn-id: branches/objc@13763 -
forced to something else by the compiler (internal rtl functions etc),
necessary for the objc branch
* fixed adding all used function result registers to the list of
registers that may need to be saved before a function call
git-svn-id: trunk@13695 -
depend on that (and correct a number of cases where this was wrong)
* set the correct subreg type for xmm x86_64 parameter registers
(resolved mantis #14067)
git-svn-id: trunk@13410 -
alignment for each memory reference (mantis #12137, and
test/packages/fcl-registry/tregistry1.pp on sparc). This also
enables better code generation for packed records in many cases.
o several changes were made to the compiler to minimise the chances
of accidentally forgetting to set the alignment of memory references
in the future:
- reference_reset*() now has an extra alignment parameter
- location_reset() can now only be used for non LOC_(C)REFERENCE,
use location_reset_ref() for those (split the tloc enum so the
compiler can catch errors using range checking)

the syntax is exactly the same as for "external", except for
the keyword. It is currently only active for Darwin targets.
It should also work at least for Linux targets, but only with
the GNU assembler (which is why it is not activated there)
+ test for this functionality

+ write the header for non-pic darwin/arm call stubs properly in aggas
* r9 is not available for general use on darwin/arm according to the llvm
code generator
git-svn-id: trunk@11862 -
method in TArmGNUAssembler, because it's cleaner (no ifdef) and it
mustn't be added for darwin (which uses TArmAppleGNUAssembler)

* Suppressed 2 unreachable code warnings.
* Now x86 compiler compiles without warnings and notes! It will be great to keep such state in future...
