-ffast-math was added in ff14092d8d with a comment that it "helps SINC
resampler to auto-vectorize". The flag is an alias for "-fno-math-errno
-funsafe-math-optimizations -ffp-contract=fast -fno-honor-infinities
-fno-honor-nans". The last two of those cause compiler complaints
because while the flag was meant for this file, it's shared across the
codebase that includes statements that operate on infinities and NaNs.
GCC 13.3 with -fopt-info-vec reports 18 vectorizations for `-O3
-ffast-math`, 17 for `-O3 -fno-math-errno -funsafe-math-optimizations
-ffp-contract=fast` and also 17 for plain `-O3`. So using the subset of
-ffast-math without the offending flags buys nothing and loses 1
vectorization.
Both GCC and Clang provide the "fast-math" pragma directive, which I add
to this one file that benefits from it, under the condition that it's
supported. -ffast-math is removed from most of the makefiles.
The point of making the default "semi-silent" (each target is printed,
but not the entire invocation verbatim) was to factor out information
about invocation to a one-time target (info) and not repeating it ever
again. With V=1, the info target is silent, because each command
invocation will be printed verbatim, which needs no herald.
The undesired side effect of me introducing the info target and making
it a dependency of the default all target is that info doesn't respect
the --silent make option, so in this use case it was more noisy, not
less.
I believe the most elegant solution that satisfies all use cases is to
stop printing info unconditionally, and instead list it explicitly in
make invocations in CI, together with the all target. Then this info is
kept available for inspection from logs, but it's not repeated on each
invocation. The intention was to make the logs easier to read and scroll
in search for new compiler warnings.
While here:
* remove input_overlay and task_overlay from linking blacklist
* move -Werror to CC invocation since C++ refuses to use it
* copy the quiet build mode from the main Makefile and make it the
default
* temporarily define DEPRECATED for gpu_old.h to allow succesful build
* replace the call to command_event() with one to retroarch_main_quit()
in a failure case
* add missing uncompr.o in Makefile.common for HAVE_BUILTINZLIB
* (3DS) Add bottom screen menu
-> User can save/load state on botom screen with thumbnail.
-> Call a save_state_to_file() when RAM state has data to write a disk.
-> If the bottom screen needs updating, swap the bottom framebuffers.
Add: SAVE/LODE STATE TO RAM
-> This is useful for devices with slow I/O
-> 3DS bottom save state use CMD_EVENT_SAVE_STATE_TO_RAM
-> 3DS bottom load state use CMD_EVENT_LOAD_STATE when RAM state has no data
-> 3DS bottom load state use CMD_EVENT_LOAD_STATE_FROM_RAM when RAM sate has data
* Rewrite path_get_state to retroarch_get_current_savestate_path
* Fix unterminated state_path
Set USE_CTRULIB_2=1 to build with libctru 2.0. When unset, this code
is compatible with the older toolchain.
Some 2.0 changes addressed rare problems in earlier versions:
- Save / restore stack pointer for init / exit
Otherwise, it could be outside of the range we deallocate.
- Run aptMainLoop in the audio driver to react correctly to sleep events
Other changes for 2.0:
- Remove ninjhax1 -- requires outdated APIs that have been removed
- Switch from __sync_arbiter to syncArbitrateAddress
- Use implicit gxCmdBuf
- Use gpuPresentBuffer for double buffering
Adds missing HAVE_7ZIP definition for griffin builds.
I have no issues with this. Browsing and loading .7z files works as it should.
Unless there's a specific reason this was removed, it can be enabled.
