The new noescape and nocallback directives can be used instead of the C
wrapper functions that are there just to avoid some parameters being
escaped to the heap.
This CL also helps demonstrate the use of the new directives in real

I've added some benchmarks to demonstrate that this CL doesn't
introduce new heap allocations when using boringcrypto:

CL 473415 allowed 5 more threads in TestWindowsStackMemory, to cover
sysmon and any new threads in future. However, during go1.22 dev cycle,
the test becomes flaky again, failing in windows-386 builder a couple of
times in CL 535975 and CL 536175 (and maybe others that haven't caught).
This CL increases the extra threads from 5 to 10, hopefully to make the
test stable again for windows-386. The theory is that Go process load a
bunch of DLLs, which may start their own threads. We could investigate
more deeply if the test still be flaky with 10 extra threads.

RtlGenRandom is a semi-undocumented API, also known as

It's definition, in cryptbase.dll, is an opaque wrapper for the
documented API ProcessPrng. Instead of using RtlGenRandom, switch to
using ProcessPrng, since the former is simply a wrapper for the latter,
there should be no practical change on the user side, other than a minor

This CL separates running shell commands and doing shell-like
operations out of the Builder type and into their own, new Shell type.
Shell is responsible for tracking output streams and the Action that's
running commands. Shells form a tree somewhat like Context, where new
Shells can be derived from a root shell to adjust their state.
The primary intent is to support "go build -json", where we need to
flow the current package ID down to the lowest level of command output
printing. Shell gives us a way to easily flow that context down.
However, this also puts a clear boundary around how we run commands,
removing this from the rather large Builder abstraction.

Currently, Builder.fmtcmd can read scriptDir without taking the output
lock. This introduces a potential data race between the read in fmtcmd
and the write in Showcmd. There's also a logical race here: because
fmtcmd doesn't know when its output is going to be printed, Showcmd
may print a "cd" command between when fmtcmd is called and when its
output is printed. As a result, it doesn't make sense to just lock
around the access in fmtcmd.
Instead, move the entire scriptDir substitution to Showcmd. This will
generally result in the same output. In the cases where Builder.run is
called with a non-empty desc, it means we may print a full path in the
comment line above output rather than substituting the script
directory. I think this is okay.
This lets us undo the workaround in CL 536355.

Currently, cmdError makes a somewhat fuzzy attempt to ensure the
package import path is part of the printed error, using a string
prefix check. Also, if it decides it does need to add the import path,
it prints it as a "go build" line, which could be misleading because
it can happen outside of "go build".
Clean up the whole code path by explicitly checking the provided error
description against Package.Desc(), and instead of emitting "go build"
in the error message, print it as "# importPath" just like we do in
the common case.

CL 529219 made an existing race with accessing Builder.scriptDir from
Builder.fmtcmd (and now also Builder.Showcmd) much more likely by
dropping a theoretically unnecessary condition from the call from
Builder.run to Builder.fmtcmd.
For an example race report, see
https://build.golang.org/log/c3cad62d0fc33a8381d2091661c685ea1fc525c4
The race is between
(*Builder).cover2() -> (*Builder).run() -> (*Builder).fmtcmd()
and various other call paths of the form
(*Builder).build() -> (*gcToolchain).* (*Builder).Showcmd() -> (*Builder).fmtcmd()
The race can be reproduced with
go install -race cmd/go
stress -p 1 go test -x -cover -a log
Return this race to its existing likelihood by putting the condition
back. This isn't a "correct" solution because the race could still
happen if the "cover" tool invoked by Builder.cover2 emits output. But
this will do for a temporary fix.

This is only supported power10/linux/PPC64. This generates smaller,
faster code by merging a pli + add into paddi.

In the Power10 rule to fold bit reversal into load, the MOVWZreg or
MOVHZreg (Zeroing out the upper bits of a word or halfword) becomes
redundant since byte reverse (BR) load clears the upper bits. Hence
removing for Power10. Similarly for < Power10 cases in the rule used to
fold bit reversal into load (Bswap), the above redundant operation is removed.

The documentation of readvarintUnsafe claims itself and readvarint are
duplicated. However, two implementation are not in synced, since when
readvarint got some minor improvements in CL 43150.
Updating readvarintUnsafe to match readvarint implementation to gain a
bit of speed. While at it, also updating its documentation to clarify
the main difference.
name time/op
ReadvarintUnsafe/old-8 6.04ns ± 2%
ReadvarintUnsafe/new-8 5.31ns ± 3%

The funcdata is encoded as varint, with the upper limit set to 1e9.
However, the stack offsets could be up to 1<<30. Thus emitOpenDeferInfo
will trigger an ICE for function with large frame size.
By using binary.PutUvarint, the frame offset could be encoded correctly
for value larger than 1<<35, allow the compiler to report the error.
Further, the runtime also do validation when reading in the funcdata
value, so a bad offset won't likely cause mis-behavior.
Fixes#52697

In the PPC64 ISA, the instruction to do an 'and' operation
using an immediate constant is only available in the form that
also sets CR0 (i.e. clobbers the condition register.) This means
CR0 is being clobbered unnecessarily in many cases. That
affects some decisions made during some compiler passes
that check for it.
In those cases when the constant used by the ANDCC is a right
justified consecutive set of bits, a shift instruction can
be used which has the same effect if CR0 does not need to be
set. The rule to do that has been added to the late rules file
after other rules using ANDCCconst have been processed in the
main rules file.
Some codegen tests had to be updated since ANDCC is no
longer generated for some cases. A new test case was added to
verify the ANDCC is present if the results for both the AND
and CR0 are used.
