A recent change was made for ppc64x to treat ANDCCconst as
a tuple, allowing ANDconst to be removed from the list
of ops. Included in that change were some improvements to the
rules to avoid some extra code, mainly the elimination of a
cmp 0 following an andi. and in some cases the following
isel. While those changes worked for most cases, in a few
cases some extra unnecessary code was generated.
Currently the snippet appears in archive/zip.(*FileHeader).Mode:
ANDCC R4,$1,R5 // andi. r5,r4,1
ANDCC R4,$16,R5 // andi. r5,r4,16
CMPW R5,R0 // cmpw r5,r0
ADDIS $0,$-32768,R5 // lis r5,-32768
OR R5,$511,R5 // ori r5,r5,511
MOVD $438,R6 // li r6,438
ISEL $2,R6,R5,R5 // isel r5,r6,r5,eq
MOVD $-147,R6 // li r6,-147
AND R6,R5,R6 // and r6,r5,r6
ANDCC R4,$1,R4 // andi. r4,r4,1
ISEL $2,R5,R6,R4 // isel r4,r5,r6,eq
The first ANDCC is never used and should not be there.
From the ssa.html file, the scheduler is not putting the Select1
close to the ISEL, which results in the flag being clobbered
before it can be used. By changing the score for a Select0 or Select1
with type Flags, the extra ANDCC does not occur.

Both FileServer and NewFileTransport can try to seek a file, specifically
when MIME type sniffing is performed. This can be somewhat surprising to an
implementer of an fs.FS, as their filesystem will appear to work until a
user tries to access a file with an unrecognized extension (which requires
type sniffing and therefore seeking). With FileServer, this results in a
"seeker can't seek" message, which is not very clear for the developer.
The issue arises because fs.FS does not require Seek, while http.FileSystem
does. Therefore, this change adds a line to the documentation of net/http's
adapter function mentioning the requirement.

In typebits.Set we check that the offset is a multiple of the
alignment, which makes perfect sense. But for values like
atomic.Int64, which has 8-byte alignment even on 32-bit platforms
(i.e. the alignment is larger than PtrSize), if it is on stack it
may be under-aligned, as the stack frame is only PtrSize aligned.
Normally we would prevent such values on stack, as the escape
analysis force values with higher alignment to heap. But for a
composite literal assignment like x = AlignedType{...}, the
compiler creates an autotmp for the RHS then copies it to the LHS.
The autotmp is on stack and may be under-aligned. Currently this
may cause an ICE in the typebits.Set check.
This CL makes it align the _offset_ of the autotmp to 8 bytes,
which satisfies the check. Note that this is actually lying: the
actual address at run time may not necessarily be 8-byte
aligned as we only align SP to 4 bytes.
The under-alignment is probably okay. The only purpose for the
autotmp is to copy the value to the LHS, and the copying code we
generate (at least currently) doesn't care the alignment beyond
stack alignment.
