Hello,
This patch series aims at enhancing GCC to emit standard DWARF in place
of the current GNAT encodings (non-standard DWARF) for a set of basic
types: dynamic arrays, variable-length records, variant parts, etc.
As most debuggers (including GDB) do not support these DWARF
descriptions
In order to accomodate the debugger's support evolution for new DWARF
constructs, we need to have an flag that controls the amount of GNAT
encodings/standard DWARF information that is emitted in the debug info.
Propagate this new parameter into the Ada front-end.

Hi all,
In this second patch I want to get to the point where I can get an enum that I
can use
to index all_architectures to get the current architecture being used, similar
to what we
do in patch 1/N.
The closest thing to what I want in aarch64-arches.def is the 3rd field which
specifies
Hi all,
This patch improves compilation times for code using the arm_neon.h intrinsics.
The problem there is that since we now wrap all the intrinsics in arm_neon.h
inside a pragma,
the midend will apply the pragma string onto every single intrinsic as an
attribute, calling
the target
Hi all,
This patch adds the documentation for the AArch64 target attributes and pragmas.
Ok for trunk?
Thanks,

Hi all,
This scan-assembler test was failing for me when testing with an explicit
/-march=armv7-a variant because
it clashed with the -mcpu=cortex-m7 and overrode it.
This patch skips the test if the user forces an incompatible -march or -mcpu
option.
The test now appears as UNSUPPORTED in
Sorry, had sent out the wrong version.
This is the right patch.

What's the ABI implication of fixing the inconsistency?

Hi all,
This patch implements target pragmas for aarch64.
The pragmas accepted are the same as for target attributes (as required).
In addition pragmas will need to redefine the target-specific preprocessor
macros if appropriate.
A new file: aarch64-c.c is added and the code from
Hi all,
These are the tests for target attributes and pragmas.
I've tried to test for the inlining rules, some of the possible errors and the
preprocessor macros changed from target pragmas.
Ok for trunk?

Hi all,
This patch fixes an ICE that I encountered while testing the series.
The testcase in the patch ICEs during builtin expansion because the testcase
is compiled with +nofp which means the builtin SIMD types are laid out
according to the nofp rules, but later when a function tagged with
Hi all,
This patch implements TARGET_SET_CURRENT_FUNCTION and defines SWITCHABLE_TARGET.
With this patch in the series, we should be far enough to get LTO option
switching to work properly.
The implementation if TARGET_SET_CURRENT_FUNCTION is pretty much a direct copy
from the rs6000 backend,
Hi all,
This patch implements the target-specific inlining rules.
The basic philosophy is that we want to definitely reject inlining if the
callee's architecture
is not a subset, feature-wise, of the caller's.
Beyond that, we want to allow inlining if the callee is always_inline.
If it's not,
Hi all,
This patch implements target attribute support via the
TARGET_OPTION_VALID_ATTRIBUTE_P hook.
The aarch64_handle_option function in common/config/aarch64/aarch64-common.c is
exported to the
backend and beefed up a bit.
The target attributes supported by this patch reflect the
The following patch fixes PR66626
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66626
The previous patch solved only one problem (the 2nd test case in the
PR). The following patch solves the all test cases.
The patch was tested and bootstrapped on x86/x86-64.
Committed as rev.
Hi,
This patch removes the device-specific filtering (for NVidia PTX) from
the parsing stages of the host compiler (for the device_type clause --
separately for C, C++ and Fortran) in favour of fully parsing the
device_type clauses, but not actually implementing anything for them
(device_type
Hi all,
This series implements the hooks required to enable SWITCHABLE_TARGET for the
aarch64 port.
This series allows the aarch64 compiler to sanely handle LTO compilation of
files compiled
with different target-specific options.
The first 5 patches refactor the option handling machinery and
Hi all,
This first patch adds a field to the processor structure that uniquely
identifies that processor.
Note that the current 'core' field is actually just the core for which to
schedule the instructions.
With this patch we get the nice property that we can reference a processor
struct by
Hi all,
This one is more meaty than the previous ones. It buffs up the parsing
functions for
the mcpu, march, mtune options, decouples them and makes them return an enum

the errors that may occur. This will allow us to use these functions in other
contexts

Hi all,
This is one of the main patches in the series.

Hi all,
In this second patch I add the transformation mentioned in the subject to

In combination with the first patch to combine, combine_simplify_rtx now picks
it up in the
