Richard Sandiford [Wed, 7 Aug 2019 18:37:21 +0000 (18:37 +0000)]
[AArch64] Reorganise aarch64-sve.md

aarch64-sve.md was getting a bit jumbled, with related operations
separated by unrelated operations.  Also, many SVE instructions need
to have several patterns due to the various ways in which predication
can be used, and it was getting hard to tell which instructions had a
complete set of patterns.

This patch therefore tries to use an explicit grouping scheme.
Banner comments are usually frowned on, but md files have been
a traditional exception (e.g. when using Mike's template for
new targets).

The patch also lists the instructions implemented by each section,
so that it's possible to search the file by instruction mnemonic.

I wouldn't be surprised if I end up having to rip out the contents
section, but I found it useful for the month or so that that I've
been using it locally.  The patch checks that the contents remain
up-to-date by running a checking script during an early stage of
the build.

No functional change intended.

Make function_code a 32-bit field

Adding SVE intrinsics on top of the existing AArch64 intrinsics blows
the 12-bit function_code in tree_function_decl.  That bitfield has no
spare bits, but it comes at the end of the structure and is preceded
by a pointer, so on LP64 hosts there's currently a 32-bit hole at end.

This patch therefore makes function_code an independent field and
moves the bitfield to the 32-bit hole.

I wondered about instead making function_code 16 bits, so that the
patch leaves 28 spare bits instead of just 12.  That seemed a bit
short-term though; I can't guarantee that we won't blow 16 bits once
the SVE2 functions are added...

If we run out of bits again, we can start chomping from the top
of the enum.  E.g. 24 bits should surely be enough, but there's
no point paying the overhead of the masking until we need it.

5 years agorework Ada EH Machine_Occurrence deallocation
Alexandre Oliva [Fri, 2 Aug 2019 18:46:51 +0000 (18:46 +0000)]
rework Ada EH Machine_Occurrence deallocation

Introduce exception handler ABI #1 to ensure single release, no access
after release of reraised Machine_Occurrences, and no failure to
re-reraise a Machine_Occurrence.

Unlike Ada exceptions, foreign exceptions do not get a new
Machine_Occurrence upon reraise, but each handler would delete the
exception upon completion, normal or exceptional, save for the case of
a 'raise;' statement within the handler, that avoided the delete by
clearing the exception pointer that the cleanup would use to release
it.  The cleared exception pointer might then be used by a subsequent
reraise within the same handler.  Get_Current_Excep.all would also
expose the Machine_Occurrence to reuse by Reraise_Occurrence, even for
native exceptions.

Under ABI #1, Begin_Handler_v1 claims responsibility for releasing an
exception by saving its cleanup and setting it to Claimed_Cleanup.
End_Handler_v1 restores the cleanup and runs it, as long as it isn't
still Claimed_Cleanup (which indicates an enclosing handler has
already claimed responsibility for releasing it), and as long as the
same exception is not being propagated up (the next handler of the
propagating exception will then claim responsibility for releasing
it), so reraise no longer needs to clear the exception pointer, and it
can just propagate the exception, just like Reraise_Occurrence.

ABI #1 is fully interoperable with ABI #0, i.e., exception handlers
that call the #0 primitives can be linked together with ones that call
the #1 primitives, and they will not misbehave.  When a #1 handler
claims responsibility for releasing an exception, even #0 reraises
dynamically nested within it will refrain from releasing it.  However,
when a #0 handler is a handler of a foreign exception that would have
been responsible for releasing it with #1, a Reraise_Occurrence of
that foreign or other Machine_Occurrence-carrying exception may still
cause the exception to be released multiple times, and to be used
after it is first released, even if other handlers of the foreign
exception use #1.

Fix gcc.dg/torture/ssa-fre-{5,7}.c failure for avr

The test assumes 32 bit integers (and pointers), and therefore
