For 386 and amd64, the compiler will use information from PGO to align certain
hot blocks in loops.  This improves performance an additional 1-1.5% at
a cost of an additional 0.1% text and binary size.  This is currently only implemented
on 386 and amd64 because it has not shown an improvement on other platforms.
Hot block alignment can be disabled with `-gcflags=[<packages>=]-d=alignhot=0`

## Assembler {#assembler}

## Linker {#linker}

Go 1.23 introduces a new `GOARM64` environment variable, which specifies the minimum target version of the ARM64 architecture at compile time. Allowed values are `v8.{0-9}` and `v9.{0-5}`. This may be followed by an option specifying extensions implemented by target hardware. Valid options are `,lse` and `,crypto`.

The `GOARM64` environment variable defaults to `v8.0`.
