This function has been marked as obsolete. In Qt 6.0 it's removed
entirely, so we must use getContentsMargin() explicitly instead
(margin() would do this for us).
Ditto for setMargin(), in which case we use setContentsMargin instead.
setMargin() would just pass its argument to all four parameters of
setContentsMargin(), so we can do the same.
This literal was deprecated in 5.14.0. Not to mention it wasn't
documented as part of the API either: see the 5.14.0 changelog here:
https://code.qt.io/cgit/qt/qtbase.git/tree/dist/changes-5.14.0?h=v5.14.0
On Qt 6.0 this define is removed entirely. To stay forward compatible,
we can make use of QStringLiteral instead.
This skips a potentially costly loop if volume is 100% or 0%,
as for former there is no need for volume adjustment,
while latter can be solved by specifying a AUDCLNT_BUFFERFLAGS_SILENT flag
This fixes numerous resource leaks, as not every return path cleaned every created resource
Now they are all managed automatically and "commited" to WASAPIStream class fields only
after it's certain they initialized properly
When a game is selected, the option to add a shortcut of the game to the desktop is given. Uses native Windows API since Qt lacks support for adding shortcuts.
FinalizeCarryOverflow didn't maintain XER[OV/SO] properly due to an
oversight. Here's the code it would generate:
0: 9c pushf
1: 80 65 3b fe and BYTE PTR [rbp+0x3b],0xfe
5: 71 04 jno b <jno>
7: c6 45 3b 03 mov BYTE PTR [rbp+0x3b],0x3
000000000000000b <jno>:
b: 9d popf
At first glance it seems reasonable. The host flags are carefully
preserved with PUSHF. The AND instruction clears XER[OV]. Next, an
conditional branch checks the host's overflow flag and, if needed, skips
over a MOV that sets XER[OV/SO]. Finally, host flags are restored with
POPF.
However, the AND instruction also clears the host's overflow flag. As a
result, the branch that follows it is always taken and the MOV is always
skipped. The end result is that XER[OV] is always cleared while XER[SO]
is left unchanged.
Putting POPF immediately after the AND would fix this, but we already
have GenerateOverflow doing it correctly (and without the PUSHF/POPF
shenanigans too). So let's just use that instead.
Happens in Super Mario Sunshine. You could probably do something similar
for b == -1 (like we do for subfic), but I couldn't find any titles that
do this.
- Case 1: d == a
Before:
41 8B C7 mov eax,r15d
41 BF 00 00 00 00 mov r15d,0
44 2B F8 sub r15d,eax
After:
41 F7 DF neg r15d
- Case 2: d != a
Before:
BF 00 00 00 00 mov edi,0
41 2B FD sub edi,r13d
After:
41 8B FD mov edi,r13d
F7 DF neg edi
