runtime, sync/atomic: use NOFRAME on arm

2018-02-12T21:41:30+00:00

This replaces frame size -4 with the NOFRAME flag in arm assembly.

This was automated with:

sed -i -e 's/\(^TEXT.*[A-Z]\),\( *\)\$-4/\1|NOFRAME,\2$0/' $(find -name '*_arm.s')

Plus three manual comment changes found by:

grep '\$-4' $(find -name '*_arm.s')

The go binary is identical before and after this change.

runtime: remove commented out code from ARM Linux boot

2017-10-16T21:12:48+00:00

The code was commented out by https://golang.org/cl/13234050 in 2013.
Let's just remove it.

runtime,runtime/cgo: save callee-saved FP register on arm

2016-05-25T06:54:28+00:00

Other GOARCHs already handle their callee-saved FP registers, but
arm was missing. Without this change, code using Cgo and floating
point code might fail in mysterious and hard to debug ways.

There are no floating point registers when GOARM=5, so skip the
registers when runtime.goarm < 6.

darwin/arm doesn't support GOARM=5, so the check is left out of
rt0_darwin_arm.s.

Fixes #14876

all: single space after period.

2016-03-02T00:13:47+00:00

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

This CL doesn't use go/doc to parse. It only addresses // comments.
It was generated with:

$ perl -i -npe 's,^(\s*// .+[a-z]\.)  +([A-Z]),$1 $2,' $(git grep -l -E '^\s*//(.+\.)  +([A-Z])')

runtime: for c-archive/c-shared, install signal handlers synchronously

2016-01-09T00:58:38+00:00

The previous behaviour of installing the signal handlers in a separate
thread meant that Go initialization raced with non-Go initialization if
the non-Go initialization also wanted to install signal handlers.  Make
installing signal handlers synchronous so that the process-wide behavior
is predictable.

Update #9896.

runtime: merge clone0 and clone

2015-04-22T16:28:57+00:00

We initially added clone0 to handle the case when G or M don't exist, but
it turns out that we could have just modified clone.  (It also helps that
the function we're invoking in clone0 no longer needs arguments.)

As a side-effect, newosproc0 is now supported on all linux archs.

runtime: shared library init support for android/arm.

2015-04-13T21:53:15+00:00

Follows http://golang.org/cl/8454, a similar CL for arm architectures.
This CL involves android-specific changes, namely, synthesizing
argv/auxv, as android doesn't provide those to the init functions.

This code is based on crawshaw@ android code in golang.org/x/mobile.

runtime: shared library runtime init for arm

2015-04-13T18:58:18+00:00

Adds the runtime initialization flow for arm akin to amd64.
In particular,we use the library initialization entry point to:
    - create a new OS thread and run the "regular" runtime init stack on
      that thread
    - return immediately from the main (i.e., loader) thread
    - at the first CGO invocation, we wait for the runtime initialization
      to complete.

Verified to work on a Raspberry Pi and an Android phone.

[dev.cc] all: edit assembly source for ARM to be more regular

2015-02-13T23:08:51+00:00

Several .s files for ARM had several properties the new assembler will not support.
These include:

- mentioning SP or PC as a hardware register
	These are always pseudo-registers except that in some contexts
	they're not, and it's confusing because the context should not affect
	which register you mean. Change the references to the hardware
	registers to be explicit: R13 for SP, R15 for PC.
- constant creation using assignment
	The files say a=b when they could instead say #define a b.
	There is no reason to have both mechanisms.
- R(0) to refer to R0.
	Some macros use this to a great extent. Again, it's easy just to
	use a #define to rename a register.
