In the gdc driver, this takes the previous fix for the Darwin D
bootstrap, and extends it to the -static-libphobos option as well.
Rather than pushing the -static-libphobos option back onto the command
line, the setting of SKIPOPT is instead conditionally removed. The same
change has been repeated for -static-libstdc++ so there is now no need
to call generate_option to re-add it.
In the gcc driver, -static-libphobos has been added as a common option,
validated, and a new outfile substition added to config/darwin.h to
correctly replace -lgphobos with libgphobos.a.
gcc/ChangeLog:
* common.opt (static-libphobos): Add option.
* config/darwin.h (LINK_SPEC): Substitute -lgphobos with libgphobos.a
when linking statically.
* gcc.c (driver_handle_option): Set -static-libphobos as always valid.
gcc/d/ChangeLog:
* d-spec.cc (lang_specific_driver): Set SKIPOPT on -static-libstdc++
and -static-libphobos only when target supports LD_STATIC_DYNAMIC.
Remove generate_option to re-add -static-libstdc++.
libphobos/ChangeLog:
* testsuite/testsuite_flags.in: Add libphobos library directory as
search path to --gdcldflags.

The PR98481 fix corrects an ABI regression in GCC 10, but we don't want to
introduce an ABI change in the middle of the GCC 10 cycle. This patch
introduces ABI v15 for the fix, which will be available but not default in
GCC 10.3; the broken behavior remains in ABI v14. Compatibility aliases
will not be generated for this change.

The following patch makes the choice between 32-bit and 64-bit DWARF formats
selectable by command line switch, rather than being hardcoded through
DWARF_OFFSET_SIZE macro.
The options themselves don't turn on debug info themselves, so one needs
to use -g -gdwarf64 or similar.

These flags can't be used at the same time as any of the other
sanitizers.
We add an equivalent flag to -static-libasan in -static-libhwasan to
ensure static linking.
The -fsanitize=kernel-hwaddress option is for compiling targeting the
kernel. This flag has defaults to match the LLVM implementation and
sets some other behaviors to work in the kernel (e.g. accounting for
the fact that the stack pointer will have 0xff in the top byte and to not
call the userspace library initialisation routines).
The defaults are that we do not sanitize variables on the stack and
always recover from a detected bug.
Since we are introducing a few more conflicts between sanitizer flags we
refactor the checking for such conflicts to use a helper function which
makes checking for such conflicts more easy and consistent.
We introduce a backend hook `targetm.memtag.can_tag_addresses` that
indicates to the mid-end whether a target has a feature like AArch64 TBI
where the top byte of an address is ignored.
Without this feature hwasan sanitization is not done.

Currently we have three vector cost models: cheap, dynamic and
unlimited. -O2 -ftree-vectorize uses “cheap” by default, but that's
still relatively aggressive about peeling and aliasing checks,
and can lead to significant code size growth.
This patch adds an even more conservative choice, which for lack of
imagination I've called “very cheap”. It only allows vectorisation
if the vector code entirely replaces the scalar code. It also
requires one iteration of the vector loop to pay for itself,
regardless of how often the loop iterates. (If the vector loop
needs multiple iterations to be beneficial then things are
probably too close to call, and the conservative thing would
be to stick with the scalar code.)
The idea is that this should be suitable for -O2, although the patch
doesn't change any defaults itself.
I tested this by building and running a bunch of workloads for SVE,
with three options:
(1) -O2
(2) -O2 -ftree-vectorize -fvect-cost-model=very-cheap
(3) -O2 -ftree-vectorize [-fvect-cost-model=cheap]
All three builds used the default -msve-vector-bits=scalable and
ran with the minimum vector length of 128 bits, which should give
a worst-case bound for the performance impact.
The workloads included a mixture of microbenchmarks and full
applications. Because it's quite an eclectic mix, there's not
much point giving exact figures. The aim was more to get a general
impression.
Code size growth with (2) was much lower than with (3). Only a
handful of tests increased by more than 5%, and all of them were
microbenchmarks.
In terms of performance, (2) was significantly faster than (1)
on microbenchmarks (as expected) but also on some full apps.
Again, performance only regressed on a handful of tests.
As expected, the performance of (3) vs. (1) and (3) vs. (2) is more
of a mixed bag. There are several significant improvements with (3)
over (2), but also some (smaller) regressions. That seems to be in
line with -O2 -ftree-vectorize being a kind of -O2.5.
The patch reorders vect_cost_model so that values are in order
of increasing aggressiveness, which makes it possible to use
range checks. The value 0 still represents “unlimited”,
so “if (flag_vect_cost_model)” is still a meaningful check.

Register the profile information in the specified section instead of using a
constructor/destructor. A pointer to the profile information generated by
-fprofile-arcs or -ftest-coverage is placed in the specified section for each
translation unit. This option disables the profile information registration
through a constructor and it disables the profile information processing
through a destructor.
I am not sure how I can test this option. One approach would be to assemble a
test file, then scan it and check that a .gcov_info section is present and no
__gcov_init() and __gcov_exit() calls are present. Is there an example for
this in the test suite?

This patch changes the mangling of __alignof__ to v111__alignof__,
making its mangling distinct from that of alignof(type) and
alignof(expr).
How we mangle ALIGNOF_EXPR now depends on its ALIGNOF_EXPR_STD_P flag,
which after the previous patch gets consistently set for alignof(type)
as well as alignof(expr).

The wording of the description of -fprofile-exclude-files is easy to
misunderstand. One can be led to believe a file is excluded only if
it matches all of the patterns, not just one. This patch tries to
clarify the function. It also adjusts the wording of
-fprofile-filter-files accordingly.

Adds the new option -fdiagnostics-plain-output, which is an alias for
several others:
-fno-diagnostics-show-caret
-fno-diagnostics-show-line-numbers
-fdiagnostics-color=never
-fdiagnostics-urls=never
The idea is that in the future, if the default behavior of diagnostics is
changed to add some fancy feature or other, then the
-fdiagnostics-plain-output option will also be changed accordingly so that
the old behavior is preserved in the presence of this option. This allows
us to use -fdiagnostics-plain-output in in the testsuite, such that the
testsuite (specifically the setting of TEST_ALWAYS_FLAGS in prune.exp)
does not need to be touched whenever diagnostics get a new look. This also
removes the need to add workarounds to compat.exp for every new option
that may be needed in a newer version of the compiler, but is not
supported in older versions.

As the testcase in the PR shows (not included in the patch, as
it seems quite fragile to observe unrolling in the IL), the introduction of
flag_cunroll_grow_size broke optimize attribute related to loop unrolling.
The problem is that the new option flag is set (if not set explicitly) only
in process_options and in rs6000_option_override_internal (and there only if
global_init_p). So, this means that while it is Optimization option, it
will only be set based on the command line -funroll-loops/-O3/-fpeel-loops
or -funroll-all-loops, which means that if command line does include any of
those, it is enabled even for functions that will through optimize attribute
have all of those disabled, and if command line does not include those,
it will not be enabled for functions that will through optimize attribute
have any of those enabled.
process_options is called just once, so IMHO it should be handling only
non-Optimization option adjustments (various other options suffer from that
too, but as this is a regression from 10.1 on the 10 branch, changing those
is not appropriate). Similarly, rs6000_option_override_internal is called
only once (with global_init_p) and then for target attribute handling, but
not for optimize attribute handling.
This patch moves the unrolling related handling from process_options into
finish_options which is invoked whenever the options are being finalized,
and the rs6000 specific parts into the override_options_after_change hook
which is called for optimize attribute handling (and unfortunately also
th cfun changes, but what the hook does is cheap) and I've added a call to
that from rs6000_override_options_internal, so it is also called on cmdline
processing and for target attribute.
Furthermore, it stops using AUTODETECT_VALUE, which can work only once,
and instead uses the global_options_set.x_... flags.

This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.
Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place. I did
not remove everything these patches brought in, for example:
- the mechanism to pass offload-target specific info from the application to
the offloading plugin - but the same mechanism is also used to
communicate number of teams and the thread limit to all offload targets.
- run_func hook in gomp_device_descr stays too, although now it is
not used. If some future offload target would like the ability to
refuse to offload some functions, it can use it. It is easy to
remove as a follow-up if it is considered clutter, though.
- configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.
- Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
from gomp-constants.h) appears in the source of the amdgcn libgomp
plugin, although I tend to think that code path is not ever used
and this patch certainly removes it from the compiler.
Nevertheless, it seems it has potential value beyond HSAIL and so
I've kept it, it can of course always be easily removed in the
future of GCN folk abandon it too.
- I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
need to stay indefinitely too just so that no future offload
target picks that number.
- I have kept dg-require-effective-target
offload_device_nonshared_as requirement of thests which have it.
It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.

Currently GIMPLE complete unroller(cunroll) is checking
flag_unroll_loops and flag_peel_loops to see if allow size growth.
Beside affects curnoll, flag_unroll_loops also controls RTL unroler.
To have more freedom to control cunroll and RTL unroller, this patch
introduces flag_cunroll_grow_size. With this patch, we can control
cunroll and RTL unroller indepently.

This patch simplifies (!!!) the logic governing the naming of dump
files and auxiliary output files in the driver, in the compiler, and
in the LTO wrapper. No changes are made to the naming of primary
outputs, there are often ways to restore past behavior, and a number
of inconsistencies are fixed. Some internal options are removed
(-auxbase and -auxbase-strip), sensible existing uses of -dumpdir and
-dumpbase options remain unchanged, additional useful cases are added,
making for what is still admittedly quite complex. Extensive
documentation and testcases provide numerous examples, from normal to
corner cases.
The most visible changes are:
- aux and dump files now always go in the same directory, that
defaults to the directory of the primary output, but that can be
overridden with -dumpdir, -save-temps=*, or, preserving past behavior,
with a -dumpbase with a directory component.
- driver and compiler now have the same notion of naming of auxiliary
outputs, e.g. .dwo files will no longer be in one location while the
debug info suggests they are elsewhere, and -save-temps and .dwo
auxiliary outputs now go in the same location as .su, .ci and
coverage data, with consistent naming.
- explicitly-specified primary output names guide not only the
location of aux and dump outputs: the output base name is also used in
their base name, as a prefix when also linking (e.g. foo.c bar.c -o
foobar creates foobar-foo.dwo and foobar-bar.dwo with -gsplit-dwarf),
or as the base name instead of the input name (foo.c -c -o whatever.o
creates whatever.su rather than foo.su with -fstack-usage). The
preference for the input file base name, quite useful for our
testsuite, can be restored with -dumpbase "". When compiling and
linking tests in the testsuite with additional inputs, we now use this
flag. Files named in dejagnu board ldflags, libs, and ldscripts are
now quoted in the gcc testsuite with -Wl, so that they are not counted
as additional inputs by the compiler driver.
- naming a -dumpbase when compiling multiple sources used to cause
dumps from later compiles to overwrite those of earlier ones; it is
now used as a prefix when compiling multiple sources, like an
executable name above.
- the dumpbase, explicitly specified or computed from output or input
names, now also governs the naming of aux outputs; since aux outputs
usually replaced the suffix from the input name, while dump outputs
append their own additional suffixes, a -dumpbase-ext option is
introduced to enable a chosen suffix to be dropped from dumpbase to
form aux output names.
- LTO dump and aux outputs were quite a mess, sometimes leaking
temporary output names into -save-temps output names, sometimes
conversely generating desirable aux outputs in temporary locations.
They now obey the same logic of compiler aux and dump outputs, landing
in the expected location and taking the linker output name or an
explicit dumpbase overrider into account.
- Naming of -fdump-final-insns outputs now follows the dump file
naming logic for the .gkd files, and the .gk dump files generated in
the second -fcompare-debug compilation get the .gk inserted before the
suffix that -dumpbase-ext drops in aux outputs.

copying gcda files around [pr93401]
Hi,
in GCC 8 we changed -fprofile-generate=<path> to use mangled absolute paths in
the <path> directory. This was necessary to avoid clashes of files when gcc is
executed from different directories to build different sources of same
filename.
However this made it difficult to build projects on setups where instrumented
build is done in one directory, feedback build in different and possibly
training happens in yet another directory structure. This happens i.e. for
Firefox builds for month or two.
This patch adds -fprofile-prefix-path that can be used to inform gcc where the
root of build directory is and strip it form the gcda filenames.
This is similar to exisitng debug-prefix-map but without the map feature since
it seems useless for profile data.
We spent quite some time with Maritn Liska discussing options and found no
better solution. I was looking how this work on LLVM and they produce single
profdata file which is then transformed into kind of simple database by
llvmprofdata tool. This database keys functions by filename and symbol name.
If you arrane two files with same name define static variable with same symbol
name this gets messedup and result in wrong info. So I think this is not very
good solution and preffer the extra option.
Bootstrapped/regtested x86_64-linux. I plan to commit it later today if there
are no complains.
I suppose our manual could have some central section on profile feedback
explaining the whole setup at one place.

This patch adds support for associating a "diagnostic_path" with a
diagnostic: a sequence of events predicted by the compiler that leads to
the problem occurring, with their locations in the user's source,
text descriptions, and stack information (for handling interprocedural
paths).
For example, the following (hypothetical) error has a 3-event
intraprocedural path:
test.c: In function 'demo':
test.c:29:5: error: passing NULL as argument 1 to 'PyList_Append' which
requires a non-NULL parameter
29 | PyList_Append(list, item);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
'demo': events 1-3
|
| 25 | list = PyList_New(0);
| | ^~~~~~~~~~~~~
| | |
| | (1) when 'PyList_New' fails, returning NULL
| 26 |
| 27 | for (i = 0; i < count; i++) {
| | ~~~
| | |
| | (2) when 'i < count'
| 28 | item = PyLong_FromLong(random());
| 29 | PyList_Append(list, item);
| | ~~~~~~~~~~~~~~~~~~~~~~~~~
| | |
| | (3) when calling 'PyList_Append', passing NULL from (1) as argument 1
|
The patch adds a new "%@" format code for printing event IDs, so that
in the above, the description of event (3) mentions event (1), showing
the user where the bogus NULL value comes from (the event IDs are
colorized to draw the user's attention to them).
There is a separation between data vs presentation: the above shows how
the diagnostic-printing code has consolidated the path into a single run
of events, since all the events are near each other and within the same
function; more complicated examples (such as interprocedural paths)
might be printed as multiple runs of events.
Examples of how interprocedural paths are printed can be seen in the
test suite (which uses a plugin to exercise the code without relying
on specific warnings using this functionality).
Other output formats include
- JSON,
- printing each event as a separate "note", and
- to not emit paths.

This patch adds support for associating a diagnostic message with an
optional diagnostic_metadata object, so that plugins can add extra data
to their diagnostics (e.g. mapping a diagnostic to a taxonomy or coding
standard such as from CERT or MISRA).
Currently this only supports associating a CWE identifier with a
diagnostic (which is what I'm using for the warnings in the analyzer
patch kit), but adding a diagnostic_metadata class allows for future
growth in this area without an explosion of further "warning_at"
overloads for all of the different kinds of custom data that a plugin
might want to add.
This version of the patch renames the overly-general
-fdiagnostics-show-metadata to -fdiagnostics-show-cwe and adds test
coverage for it via a plugin.
It also adds a note to the documentation that no GCC diagnostics
currently use this; it's a feature for plugins (and, at some point,
I hope, the analyzer).

GCC currently defaults to -fcommon. As discussed in the PR, this is an ancient
C feature which is not conforming with the latest C standards. On many targets
this means global variable accesses have a codesize and performance penalty.
This applies to C code only, C++ code is not affected by -fcommon. It is about
time to change the default.

This was first submitted many years ago
https://gcc.gnu.org/ml/gcc-patches/2010-10/msg02468.html
The command line option -fcallgraph-info is added and makes the
compiler generate another output file (xxx.ci) for each compilation
unit (or LTO partitoin), which is a valid VCG file (you can launch
your favorite VCG viewer on it unmodified) and contains the "final"
callgraph of the unit. "final" is a bit of a misnomer as this is
actually the callgraph at RTL expansion time, but since most
high-level optimizations are done at the Tree level and RTL doesn't
usually fiddle with calls, it's final in almost all cases. Moreover,
the nodes can be decorated with additional info: -fcallgraph-info=su
adds stack usage info and -fcallgraph-info=da dynamic allocation info.
