This broke formatting the system memory; see https://bugs.dolphin-emu.org/issues/13176. After calling ticket.DeleteTicket(), ticket.m_bytes was 0-length, but calling ticket.IsV1Ticket() still attempted to read from m_bytes.
This was introduced in 2fd9852ca8, although it didn't actually cause a crash until 929fba08e7.
This resulted in the labels being solid black even when audio stretching is disabled the first time the settings are opened, but then properly being greyed out after changing a setting (even the audio backend or DSP emulation engine, not just whether audio stretching is enabled).
This very much isn't a build configuration that we're going to ship,
but I want to be able to tell people that they can build it on their
own if they really want to see how terribly it performs :)
Just like before, you'll need to edit two lines in app/build.gradle to
define ENABLE_GENERIC=ON and actually enable armeabi-v7a if you want an
armeabi-v7a build. This commit just fixes some compilations errors that
crop up if you do so.
Before these changes you could tell Dolphin to convert a game file into the same format it is already in, leading to the FileDialog using the input path as the default destination path
An unsuspecting user could then click Save and Dolphin would try to convert the input file by writing the destination file on top of it... leading to an I/O error and the input file being entirely removed
Doing so is not allowed (presumably because compilers are allowed to use a different algorithm for allocating between the two/store extra data such as the length of the array before the pointer).
This bug existed in the original implementation at https://web.archive.org/web/20140708092159/http://www.hydrogenaud.io/forums/index.php?showtopic=52235 and causes Valgrind to emit a warning. Note that this ended up happening even if DSPLLE and the DPL decoder are not enabled in Dolphin.
This fixes a regression from 592ba31. When `a` was a constant 0 and `b`
was a non-constant 0x80000000, the 32-bit negation operation would
overflow, causing an incorrect result. The sign extension needs to happen
before the negation to avoid overflow.
Note that I can't merge the SXTW and NEG into one instruction.
NEG is an alias for SUB with the first operand being set to ZR,
but "SUB (extended register)" treats register 31 as SP instead of ZR.
I've also changed the order for the case where `a` is a constant
0xFFFFFFFF. I don't think the order actually affects correctness here,
but let's use the same order for all the cases since it makes the code
easier to reason about.
