When linking with -flto and -save-temps, various
temporary files are created in /tmp.
The same happens when invoking the driver with @file

Ideally, the linker will be queried for its version and that will be
used to determine capabilities that cannot be discovered from
reasonable configuration testing.
When building cross tools, this might not be possible, and we have
strategies for providing useful defaults. These are adjusted here to
refect current choices.
gcc/ChangeLog:
* config/darwin.h (MIN_LD64_NO_COAL_SECTS): Adjust.
Amend handling for LD64_VERSION fallback defaults.
|
|
The darwinN.h headers (with the sole exception of darwin7.h,
which contains a target macro definition) now only contain
values that set fall-backs for cross-compilations, these can
be provided from the config.gcc script which means we no longer
need the darwinN.h - so delete them.
gcc/ChangeLog:
* config.gcc: Compute default version information
from the configured target. Likewise defaults for
ld64.
* config/darwin10.h: Removed.
* config/darwin12.h: Removed.
* config/darwin9.h: Removed.
* config/rs6000/darwin8.h: Removed.

Darwin defines ASM_OUTPUT_ALIGNED_DECL_COMMON which is used in
preference to ASM_OUTPUT_ALIGNED_COMMON, which makes the latter
definition dead code. Remove this.
gcc/ChangeLog:
* config/darwin9.h (ASM_OUTPUT_ALIGNED_COMMON): Delete.
|
|
We now need a modern (C++11) toolchain to bootstrap GCC, so there's no
need to skip the stack protect for Darwin < 9.

* config/darwin.h (STACK_CHECK_STATIC_BUILTIN): .. to here.

There is no need to make the LINK_GCC_C_SEQUENCE_SPEC conditional on
configuration parameters, it is adequately conditionalized on the
macosx-version-min.
gcc/ChangeLog:
* config/darwin10.h (LINK_GCC_C_SEQUENCE_SPEC): Move from
here...
* config/darwin.h (LINK_GCC_C_SEQUENCE_SPEC): ... to here.
|

The darwinN.h headers were (presumably) introduced to allow specs to be
adjusted when there was no mmacosx-version-min handling, or that was
considered unreliable.
We have version-specific specs for the values that have configuration
data, and the version is set in the driver (so may be considered
reliably present).
Some of the 'darwinN.h' content has become dead code, and the reminder
is either conditionalised on version information (or is setting values
used as fall-backs in cross-compilations).
With the changes needed for Darwin20 / macOS 11 the 'darwnN.h' headers
are now too unwieldy to be useful - so this series moves the relevant
specs definitons to the common 'darwin.h' header and then finally uses
the config.gcc script to supply the fall-back defaults for cross-
compilations.
We can then delete all but the main header, since the darwinN.h are
unused.
This change moves a spec from darwin10.h to the main darwin.h
target header.
gcc/ChangeLog:
* config/darwin10.h (LINK_GCC_C_SEQUENCE_SPEC): Move the spec
for the Darwin10 unwinder stub from here ...
* config/darwin.h (LINK_COMMAND_SPEC_A): ... to here.

The toolchain now requires a C++11 compiler to bootstrap and
none of the older Darwin toolchains which were based on stabs
debugging are suitable. We can simplify the debug setup now.
gcc/ChangeLog:
* config/darwin.h (DSYMUTIL_SPEC): Default to DWARF
(ASM_DEBUG_SPEC):Only define if the assembler supports
stabs.
(PREFERRED_DEBUGGING_TYPE): Default to DWARF.
(DARWIN_PREFER_DWARF): Define.
* config/darwin9.h (PREFERRED_DEBUGGING_TYPE): Remove.
(DARWIN_PREFER_DWARF): Likewise
(DSYMUTIL_SPEC): Likewise.
(COLLECT_RUN_DSYMUTIL): Likewise.
(ASM_DEBUG_SPEC): Likewise.
(ASM_DEBUG_OPTION_SPEC): Likewise.

If the target is configured such that -mlong-call is passed
by default, the function calls these tests are trying to detect
by scanning the assembly file are performed using long calls,
like so:
| foo:
| @ memset-inline-2.c:12: memset (a, -1, 14);
| mov r2, #14 @,
| mvn r1, #0 @,
| ldr r0, .L2 @,
| ldr r3, .L2+4 @ tmp112,
| bx r3 @ tmp112
Looking at .L2 (and in particular at .L2+4):
| .L2:
| .word a
| .word memset <<<---
This change adds -mno-long-calls to the list of compiler options
to make sure we generate short call code, allowing the assembly
matching to pass.
This is added unconditionally to the dg-options (as opposed to using
dg-additional-options) because this test is already specific to ARM
targets, and -mno-long-calls is available on all ARM targets.
for gcc/testsuite/ChangeLog
* gcc.target/arm/memset-inline-2.c: Add -mno-long-calls to
the test's dg-options.
* gcc.target/arm/pr78255-2.c: Likewise.

This test currently fails on VxWorks 7 SR06x0 targets when in kernel
mode, because it expects a discrepancy between built-in and system
intmax_t for all VxWorks targets when in kernel mode. Fortunately,
this has now been fixed when targetting VxWorks 7 SR06x0, so this
commit adjusts the "dg-error" condition to exclude newer versions of
VxWorks 7.

The implicit -mlong-calls used in our vxworks configurations changes

This patch brings the test output in line with the expectations, with

The implicit -mlong-calls from our vxworks configurations makes the
tail-call instructions differ from those expected by the
no_unique_address tests in gcc.target/arm.
This patch adds -mno-long-calls to the compilation commands, so that
we generate the expected sequences.

* g++.target/arm/no_unique_address_1.C: Add -mno-long-calls.
* g++.target/arm/no_unique_address_2.C: Likewise.

The headmerge tests pass a constant to conditional calls, so that the
same constant is always passed to a function, though it's a different
function depending on which path is taken.
The test checks that the constant appears only once in the assembly
output, as a means to verify that the insns setting up the argument
are unified: they appear as separate insns up to jump2, where
crossjump identifies a common prefix to all conditional paths and
unifies them.
Alas, with -mlong-calls, that we enable in our arm-vxworks
configurations, the argument register is loaded after loading the
callee address into another register. Since each path calls a
different function, there's no common initial code sequence for
crossjump to unify, and the argument register set up remains separate,
so the test fails.
Though it would surely be desirable for the compiler to perform the
unification of the argument register setting up, this patch merely
avoids the effects of -mlong-calls, with an explicit -mno-long-calls.
for gcc/testsuite/ChangeLog
* gcc.target/arm/headmerge-1.c: Add -mno-long-calls.
* gcc.target/arm/headmerge-2.c: Likewise.

The implicit -mlong-calls used in our arm-vxworks configurations
changes the register allocation patterns in the arm/fp16-aapcs-2.c
test: r3 ends up used in the long-call sequence, and we end up using
ip as a temporary, which doesn't match the expected mov patterns.
This patch adds an explicit -mno-long-calls for the generated code to
match the expectation.
for gcc/testsuite/ChangeLog
* gcc.target/arm/fp16-aapcs-2.c: Use -mno-long-calls.
