Prior to this CL, flags such as NOSPLIT
on ATEXT Progs were stored in From3.Offset.
Some but not all of those flags were also
duplicated into From.Sym.Attribute.
This CL migrates all of those flags into
From.Sym.Attribute and stops creating a From3.
A side-effect of this is that printing an
ATEXT Prog can no longer simply dump From3.Offset.
That's kind of good, since the raw flag value
wasn't very informative anyway, but it did
necessitate a bunch of updates to the cmd/asm tests.
The reason I'm doing this work now is that
avoiding storing flags in both From.Sym and From3.Offset
simplifies some other changes to fix the data
race first described in CL 40254.
This CL almost passes toolstash-check -all.
The only changes are in cases where the assembler
has decided that a function's flags may be altered,
e.g. to make a function with no calls in it NOSPLIT.
Prior to this CL, that information was not printed.

was necessary prior to Go 1.4, where it needed to match names like
"windows.c", but now it's gratuitously different from go/build. This
led to a bug chase to figure out why "stubs_nonlinux.go" was not being

Change shouldbuild to require an "_" before the GOOS and GOARCH in a

When casting an ideal to complex{64,128}, for example during the
evaluation of
var a = complex64(0) / 1e-50
we want the compiler to report a division-by-zero error if a divisor
would be zero after the cast.
We already do this for floats; for example
var b = float32(0) / 1e-50
generates a 'division by zero' error at compile time (because
float32(1e-50) is zero, and the cast is done before performing the
division).
There's no such check in the path for complex{64,128} expressions, and
no cast is performed before the division in the evaluation of
var a = complex64(0) / 1e-50
which compiles just fine.
This patch changes the convlit1 function so that complex ideals
components (real and imag) are correctly truncated to float{32,64}
when doing an ideal -> complex{64, 128} cast.

A recent performance improvement for PPC64.rules introduced a

the assembler was not detecting the incorrect offset and still generated
the instruction even though it was invalid.
This fix changes the PPC64.rules for the moves that are now failing
to include the correct alignment checks, along some additional testcases
for gc/ssa for the failing alignments.
I will add a fix to the assembler to detect incorrect offsets in

was broken by c03e75e5. In particular, innerloop does not only account
for loops, but also for switches and selects. Swap it by bools that
track whether breaks and continues should be allowed.
While at it, improve the wording of errors for breaks that are not where
they should be. Change "loop" by "loop, switch, or select" since they
can be used in any of those.
And add tests to make sure this isn't broken again. Use a separate func

when exporting it, to preserve reproducibility.
We sort using exactly the same mechanism
that the export code (dtypesym) uses.
Failure to do that led to non-deterministic builds (#19872).
Since we've already calculated the Type's export name,
we could pass it to dtypesym, sparing it a bit of work.
That can be done as a future optimization.
