During emulation, when LocalGame has a value but CurrentRun
doesn't, we want to read from LocalGame, not CurrentRun. This
change exposes a LAYER_ACTIVE option that handles this correctly.
By calling ZSTD_CCtx_setPledgedSrcSize, we can let zstd know
how large a chunk is going to be before which start compressing
it, which lets zstd avoid allocating more memory than needed
for various internal buffers. This greatly reduces the RAM usage
when using a high compression level with a small chunk size,
and doesn't have much of an effect in other circumstances.
A side effect of calling ZSTD_CCtx_setPledgedSrcSize is that
zstd by default will write the uncompressed size into the
compressed data stream as metadata. In order to save space,
and since the decompressed size can be figured out through
the structure of the RVZ format anyway, we disable writing
the uncompressed size by setting ZSTD_c_contentSizeFlag to 0.
This shader has been rendered nonfunctional due to the removal of the function SampleFontLocation, which was never implemented in VideoCommon. The last reference to SampleFontLocation was located in the OGL video backend. It was removed in this commit: f039149198 (diff-24125a6c968a8aca9cadd977d4b9d68f), where many functions were moved to video common, among other things.
This shader should be removed so it does not confuse users with the error that it causes. Alternatively, it could be rewritten so it is compatible with modern versions of Dolphin. I am not familiar with GLSL, so this is currently beyond my skill set.
Unlike Super Paper Mario, this game doesn't crash as soon as you
try to start it, but rather if you try to skip a certain cutscene.
Thanks to JMC for letting me know about this.
For the non-packed variant of this instruction, a MOVSD instruction was
generated to copy only the lower 64 bits of XMM1 to the destination
register. This was done in order to keep the destination register's
upper half intact.
However, when register c and the destination register are the same,
there is no need for this copy. Because the registers match and due to
the way the mask is generated, BLENDVPD will end up taking the upper
half from the destination register, as intended.
Additionally, the MOVAPS to copy Rc into XMM1 can also be skipped.
