During the parallel section of compilation, we limit the amount of
parallelism to prevent scheduler churn. We do this with a worker
scheduler, but it does not have insight on when a compilation is blocked
due to lock contention.
The symbol table was protected with a lock. While most lookups were
quick lock->read->unlock affairs, sometimes there would be
initialization logic involved. This caused every lookup to stall,
waiting for init. Since our worker scheduler couldn't see this, it would
not launch new goroutine to "cover" the gap.
Fix by splitting the symbol lock into 2 cases, initialization and
lookup. If symbols need initialization simultaneously, they will wait
for each other, but the common case of looking up a symbol will be
handled by a syncmap. In practice, I have yet to see this lock being
blocked on.
Additionally, get rid of the scheduler goroutine and have each
compilation goroutine grab work from a central queue. When multiple
compilations finished at the same time, the work scheduler would
sometime not get run immediately. This ended up starving the system of
work.
These 2 changes together cuts -1.37% off the build time of typescriptgo
on systems with a lot of cores (specifically, the c3h88 perf builder).
Updates #73044.

When a function call exceeds the immediate value range of the instruction,
a trampoline is required to assist in the jump. Trampoline is only omitted
when plt is needed; otherwise, a check is required.

Both the MULW and MUL instructions point to the mul.w instruction
in the loong64 ISA. Previously, MULW was not encoded; now it is
encoded and used as an alias for MUL.
The same applies to the following instructions: ADD, SUB, DIV.
For consistency, we have added additional aliases for DIVU, REM and REMU.

log2
In several places the integer log2 is calculated using loops or similar
mechanisms. math/bits.Len* provide a simpler and more efficient
mechanisms for this.
Annoyingly, every usage has slightly different ideas of what "log2"
means and how non-positive inputs should be handled. I verified the
replacements in each case by comparing the result for inputs from 0
to 1<<16.

Rework these tests such that they are built on all architectures and
actually executed when run on riscv64. This increases the likelihood
of catching code generation issues, especially those that impact
relocations. Also ensure that the generated assembly includes the
instruction sequence that is expected for the large branch/call/jump.

Host libgcc.a (among other libraries) on loong64 systems may contain
such relocs if built with the "medium" code model and/or linker
relaxation, which is increasingly the case. Make the internal linker
aware of these for cgo interopability going forward.
While at it, fix some of the comments for the loong64-specific
RelocTypes.

In dynlink mode, we rewrite reference to a global variable to
a load from the GOT. Currently this code does not handle the case
that the global reference is in From3 of a Prog. Most instructions
don't expect a memory operand in From3, but some do, like
VGF2P8AFFINEQB. Handle this case.

riscv64
Make use of compressed instructions on riscv64 - add a compress
pass to the end of the assembler, which replaces non-compressed
instructions with compressed alternatives if possible.
Provide a `compressinstructions` compiler and assembler debug
flag, such that the compression pass can be disabled via
`-asmflags=all=-d=compressinstructions=0` and
`-gcflags=all=-d=compressinstructions=0`. Note that this does
not prevent the explicit use of compressed instructions via
assembly.
Note that this does not make use of compressed control transfer
instructions - this will be implemented in later changes.
Reduces the text size of a hello world binary by ~121KB
and reduces the text size of the go binary on riscv64 by ~1.21MB
(between 8-10% in both cases).

instructions on riscv64
Enable the use of compressed instructions on riscv64 by reducing
the PC quantum to two bytes and reducing the minimum instruction
length to two bytes. Change gostartcall on riscv64 to land at
two times the PC quantum into goexit, so that we retain four byte
alignment and revise the NOP instructions in goexit to ensure that
they are never compressed. Additionally, adjust PCALIGN so that it
correctly handles two byte offsets.

Manually resolved some conflicts:
- Use internal/strconv for simd.String, remove internal/ftoa
- prove.go is just copied from the one on the main branch. We
have cherry-picked the changes to prove.go to main branch, so
our copy is identical to an old version of the one on the main
branch. There are CLs landed after our cherry-picks. Just copy
it over to adopt the new code.

Add support for compressed instructions in the RISC-V assembler. This
implements instruction validation and encoding for all instructions in
the "C" extension.
It is worth noting that the validation and encoding of these instructions
is far more convoluted then the typical instruction validation and
encoding. While the current model has been followed for now, it would be
worth revisiting this in the future and potentially switching to a table
based or even per-instruction implementation.
Additionally, the current instruction encoding is lacking some of the bits
needed for compressed instructions - this is solved by compressedEncoding,
which provides the missing information. This will also be addressed in the
future, likely by changing the instruction encoding format.
Updates #71105

Replace the extractBitAndShift function with an encodeBitPattern function.
This allows the caller to specify a slice of bits that are to be extracted

results.

This change mechanically replaces all occurrences of interface{}

std and cmd, minus their vendor trees.
Since this fix is relatively numerous, it gets its own CL.
Also, 'go generate go/types'.

Large integer constants can take up to 4 instructions to encode.
We can encode some large constants with a single instruction, namely
those which are bit patterns (repetitions of certain runs of 0s and 1s).
Often the constants we want to encode are *close* to those bit patterns,
but don't exactly match. For those, we can use 2 instructions, one to
load the close-by bit pattern and one to fix up any mismatches.
The constants we use to strength reduce divides often fit this pattern.
For unsigned divides by 1 through 15, this CL applies to the constant
for N=3,5,6,10,12,15.
Triggers 17 times in hello world.

Avoid needing an unsafe section to store LR and adjust SP

This is also a few instructions shorter as the large

Add support for the Pointer Authentication Code instructions
required for the ELF ABI when enabling PAC aware binaries.
This allows for assembly writers to add PAC instructions where needed to
support this ABI. Follow up work is to enable the compiler to emit these
instructions in the appropriate places.
The TL;DR for the Linux ABI is that the prologue of a function that
pushes the link register (LR) to the stack, signs the LR with a key
managed by the operating system and hardware using a PAC instruction,
like "paciasp". The function epilog, when restoring the LR from the
stack will verify the signature, using an instruction like "autiasp".
This helps prevents attackers from modifying the return address on the
stack, a common technique for ROP attacks.
Details on PAC can be found here:
- https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/enabling-pac-and-bti-on-aarch64
- https://developer.arm.com/documentation/109576/0100/Pointer-Authentication-Code

go1.26's vet printf checker can associate the printf-wrapper
property with local vars and struct fields if they are assigned
from a printf-like func literal (CL 706635). This leads to better
detection of mistakes.

Instead of storing LR (the return address) at 0(SP) and the FP
(parent's frame pointer) at -8(SP), store them at framesize-8(SP)
and framesize-16(SP), respectively.
We push and pop data onto the stack such that we're never accessing
anything below SP.
The prolog/epilog lengths are unchanged (3 insns for a typical prolog,
2 for a typical epilog).
We use 8 bytes more per frame.
Typical prologue:
STP.W (FP, LR), -16(SP)
MOVD SP, FP
SUB $C, SP
Typical epilogue:
ADD $C, SP
LDP.P 16(SP), (FP, LR)
RET
The previous word where we stored LR, at 0(SP), is now unused.
We could repurpose that slot for storing a local variable.
The new prolog and epilog instructions are recognized by libunwind,
so pc-sampling tools like perf should now be accurate. (TODO: except
maybe after the first RET instruction? Have to look into that.)
Update #73753 (fixes, for arm64)
Update #57302 (Quim thinks this will help on that issue)
