cmd/trace: merge testdata debugging tools into the trace tool

Currently internal/trace/testdata contains three debugging tools which
were written early in the trace rewrite for debugging. Two of these are
completely redundant with go tool trace -d=1 and go tool trace -d=2. The
only remaining one landed in the last cycle and could easily also be
another debug mode.

This change thus merges gotraceeventstats into go tool trace as a new
debug mode, and updates the debug mode flag (-d) to accept a string,
giving each mode a more descriptive name.

runtime: add ERMS-based memmove support for modern CPU platforms

2KB when the useAVXmemmove global variable is false and the CPU supports
the ERMS feature.

This feature is currently only enabled on CPUs in the Sandy Bridge (Client)
, Sandy Bridge (Server), Ivy Bridge (Client), and Ivy Bridge (Server)
microarchitectures.

For modern Intel CPU microarchitectures that support the ERMS feature, such
as Ice Lake (Server), Sapphire Rapids , REP MOVSB achieves better
performance than the AVX-based copy currently implemented in memmove.

9 months agoruntime: avoid multiple records with identical stacks from MutexProfile
Nick Ripley [Tue, 16 Jul 2024 11:15:22 +0000 (07:15 -0400)]
runtime: avoid multiple records with identical stacks from MutexProfile

When using frame pointer unwinding, we defer frame skipping and inline
expansion for call stacks until profile reporting time. We can end up
with records which have different stacks if no frames are skipped, but
identical stacks once skipping is taken into account. Returning multiple
records with the same stack (but different values) has broken programs
which rely on the records already being fully aggregated by call stack
when returned from runtime.MutexProfile. This CL addresses the problem
by handling skipping at recording time. We do full inline expansion to
correctly skip the desired number of frames when recording the call
stack, and then handle the rest of inline expansion when reporting the
profile.

The regression test in this CL is adapted from the reproducer in
https://github.com/grafana/pyroscope-go/issues/103, authored by Tolya
Korniltsev.

Fixes #67548

This reapplies CL 595966.
The original version of this CL introduced a bounds error in
MutexProfile and failed to correctly expand inlined frames from that
call. This CL applies the original CL, fixing the bounds error and
adding a test for the output of MutexProfile to ensure the frames are
expanded properly.

strings: re-introduce noescape wrapper

builder copyCheck code.

However, internal/abi is a runtime package, which can not be built with

runtime: avoid multiple records with identical stacks from MutexProfile

When using frame pointer unwinding, we defer frame skipping and inline
expansion for call stacks until profile reporting time. We can end up
with records which have different stacks if no frames are skipped, but
identical stacks once skipping is taken into account. Returning multiple
records with the same stack (but different values) has broken programs
which rely on the records already being fully aggregated by call stack
when returned from runtime.MutexProfile. This CL addresses the problem
by handling skipping at recording time. We do full inline expansion to
correctly skip the desired number of frames when recording the call
stack, and then handle the rest of inline expansion when reporting the
profile.

CL 327651 rewrites a, b = f() to use temporaries when types are not
identical. That would leave OAS2 node appears in body of init function
for global variables initialization. The staticinit pass is not updated
to handle OAS2 node, causing ICE when compiling global variables.

To fix this, handle OAS2 nodes like other OAS2*, since they mostly
necessitate dynamic execution anyway.

Fixes #68264

10 months agocmd/link: don't disable memory profiling when pprof.WriteHeapProfile is used

cmd/link: don't disable memory profiling when pprof.WriteHeapProfile is used

We have an optimization that if the memory profile is not consumed
anywhere, we set the memory profiling rate to 0 to disable the
"background" low-rate profiling. We detect whether the memory
profile is used by checking whether the runtime.MemProfile function
is reachable at link time. Previously, all APIs that access the
memory profile go through runtime.MemProfile. But the code was
refactored in CL 572396, and now the legacy entry point
WriteHeapProfile uses pprof_memProfileInternal without going
through runtime.MemProfile. In fact, even with the recommended
runtime/pprof.Profile API (pprof.Lookup or pprof.Profiles),
runtime.MemProfile is only (happen to be) reachable through
countHeap.

Change the linker to check runtime.memProfileInternal instead,
which is on all code paths that retrieve the memory profile. Add
a test case for WriteHeapProfile, so we cover all entry points.

Fixes #68136.

cmd/compile: fix mis-compilation when switching over channels

common type, emitting the implicit conversion if any of the case values
are not assignable to the tag value's type.

However, the Go spec definition of equality is non-transitive for

values comparison.
