      cmd/link: fix duplicated "unresolved inter-package jump" errors · 289ab304
      Iskander Sharipov authored 
      This is extension to https://golang.org/cl/113955 that handled
duplicated "unresolved relocation" errors.

For platforms with trampoline support, additional error is generated
per each undefined symbol. This breaks TestUndefinedRelocErrors test
on these platforms.

Proposed fix:

	1. Changes error text to be identical to normal undefined reloc.
	   If relocation is undefined, jump to it will be unresolved
	   as well.

	2. Introduces a map that can be used by all sites that
	   handle this kind of errors which makes it easier
	   to report such errors exactly once.

Errors on ppc64 before this change (note first 4 lines):

	main.defined1: unresolved inter-package jump to main.undefined()
	main.defined1: unresolved inter-package jump to main.undefined()
	main.defined2: unresolved inter-package jump to main.undefined()
	main.defined2: unresolved inter-package jump to main.undefined()
	main.defined1: relocation target main.undefined not defined
	main.defined2: relocation target main.undefined not defined
	runtime.main_main·f: function main is undeclared in the main package

After this change:

	main.defined1: relocation target main.undefined not defined
	main.defined2: relocation target main.undefined not defined
	runtime.main_main·f: function main is undeclared in the main package

Because of (1), errors output is the same on all platforms now.

Fixes #25753

      misc/wasm: set non-empty default for os.Args · 96faeb0b
      Richard Musiol authored 
      os.Args is usually never empty and the flag package panics if it is.
This commit makes os.Args default to ["js"] for js/wasm.

      runtime: fix pprof livelock on arm · afae876b
      philhofer authored 
      On 32-bit architectures without native 64-bit atomic instructions,
64-bit atomics are emulated using spinlocks. However,
the sigprof handling code expects to be able to perform
64-bit atomic operations in signal handlers. Spinning on an
acquired spinlock in a signal handler leads to a livelock.
This is issue #20146.

The original fix for #20146 did not include arm in
the list of architectures that need to work around portability
issues in the sigprof handler code. The unit test designed to
catch this issue does not fail on arm builds because arm uses
striped spinlocks, and thus the livelock takes many minutes
to reproduce. This is issue #24260. (This patch doesn't completely
fix #24260 on go1.10.2 due to issue #25785, which is probably
related to the arm cas kernel helpers. Those have been removed
at tip.)

With this patch applied, I was able to run the reproducer for
issue #24260 for more than 90 minutes without reproducing the
livelock. Without this patch, the livelock took as little as
8 minutes to reproduce.

Fixes #20146
Updates #24260

      cmd/cover: fix TestCoverHTML on Plan 9 · abeac091
      David du Colombier authored 
      CL 116975 added TestCoverHTML. However, this test is failing
on Plan 9, because the GNU diff tool is called "ape/diff"
instead of "diff" on Plan 9.

This change replaces the "diff" command by the "ape/diff"
command on Plan 9.

Fixes #25795.

      cmd/compile: mark BS{F,R}L as clobbering flags · 29e5a81e
      Keith Randall authored 
      Turns out it doesn't currently matter, as these ops are always issued
together with a BTSL which does clobber flags. So I can't write a test
that currently fails. But better to be future-proof.

BS{F,R}Q generates flags, so it doesn't need to be marked as clobbering.
