At higher resolutions it takes too much time to save a screenshot at the
maximum compression level. So let's allow the user to set the
compression level.
This re-uses the png_compression_level setting. The default compression
level is 1 for speed, but if the user wishes to increase the compression
level (without using an external tool) and doesn't mind if the
screenshot takes more time to save then they can increase the
compression level up to a maximum of 9 (which can take quite a while).
Fixes#1527.
1. All POSIX shells support $(...) syntax [1], including /bin/sh. shellcheck
warns about it.
2. [[ won't work in /bin/sh [2], so use [ everywhere. I wonder why it worked
now, perhaps the test was running on a system where /bin/sh -> /bin/bash.
3. In POSIX sh, string indexing is undefined. [SC2039]. Unfortunately, this
means we require a subprocess: https://wiki.ubuntu.com/DashAsBinSh. Very
ugly.
4. In POSIX sh, arrays are undefined. We seem to use $flags as an array
after constructing it by string concatenation. I tried to verify that
this has the same effect as just passing the quoted string in bash:
bash-3.2$ flags="-DCMAKE_GOOK"
bash-3.2$ flags="$flags -DCMAKE_MOARMA"
bash-3.2$ flags="$flags -DCMAKE_URURURUR"
bash-3.2$ ./argv $flags
0: ./argv
1: -DCMAKE_GOOK
2: -DCMAKE_MOARMA
3: -DCMAKE_URURURUR
bash-3.2$ ./argv "${flags[@]}"
0: ./argv
1: -DCMAKE_GOOK -DCMAKE_MOARMA -DCMAKE_URURURUR
bash-3.2$ ./argv "$flags"
0: ./argv
1: -DCMAKE_GOOK -DCMAKE_MOARMA -DCMAKE_URURURUR
bash-3.2$
5. Enable exit on unknown variable (-u). All variables should be known,
otherwise we have an error in the script. shellcheck doesn't warn so I
think it's fine.
Apart from shellcheck(1), I also ran checkbashisms(1). The latter only
reported that "command -v" might not be available in other shells.
Apparently only ash(1) doesn't understand it.
NOTE: Why are we even trying to support pre-Mavericks (Darwin < 13) OSX? We
don't even support the most modern OSX (El Capitan) fully yet. OSX upgrades
are free and generally don't leave old machines behind. Most machines made
after 2009 can upgrade to El Capitan, AFAIK. I also believe that systems
that have all the utilities and libraries necessary to build PCSX2 will have
/bin/bash >= 3.x.
NOTE 2: Does cmake/ninja generate the same type of output in
compile_commands.json?

If the dev/verbose logging option is enabled and the game requires
automatic gamefixes, the console log will always scroll to the bottom
when the scrollbar is released since a new log message will be output
when emulation unpauses.
This could be quite annoying when checking a log while the game is
running. The behaviour doesn't seem to be all that useful anymore
(previously it was useful to work around a GUI bug where the automatic
gamefixes/widescreen patches/cheats menu options didn't apply
immediately) and only works on Windows, so let's remove it.
MIPSAnalyst.cpp:124:9: warning: ‘takeBranch’ may be used uninitialized in this function [-Wmaybe-uninitialized]
else if (sure && !takeBranch)
False positive as sure will be false but safer this way
Templace is nicer but give a hard time to compiler.
New version compile in both gcc&clang without hack
v2: add an uptr cast too for VS2013 sigh...
v3: use an ugly function pointer cast to please VS2013
PNG_LIBRARIES adds both libpng and zlib to the command line.
PNG_LIBRARY only adds libpng to the linker command line, and the cmake
documentation also suggests not to use it.
Value seems wrongly rounded and you can't distinguish 0xFFFF from 0xFFFE
Instead check that depth is constant for the draw call and the value from the vertex buffer
Fix recent regression on GTA (and likely various games)
In FB_ONLY mode the alpha test impacts (discard) only the depth value.
If there is no depth buffer, we don't care about depth write. So alpha
test is useless and we can do the draw with a single draw call and no program
switch
Various distribution still ship the true old shell to win 1 second at startup.
Besides, bash syntax is no way better
Not fully tested, some bashism might remain for some options but at least you can
do a standard build
Extend GSVector to support float move
Initial code likely used integer move for performance reason. However due to
the nan correction, register is now in float domain.
It is done too late.
CID 168625 (#1 of 1): Dereference before null check (REVERSE_INULL)
check_after_deref: Null-checking this->cpu suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
I hope it wasn't done on purpose.
CID 168624 (#1 of 1): Missing break in switch (MISSING_BREAK)
unterminated_case: The case for value CMD_CONFIG_MODE is not terminated by a 'break' statement.
CID 168626 (#1 of 1): Uninitialized scalar field
uninit_member: Non-static class member m_end_block is not initialized in this constructor nor in any functions that it calls.
