all: add GOOS=ios

2020-09-23T18:12:59+00:00

Introduce GOOS=ios for iOS systems. GOOS=ios matches "darwin"
build tag, like GOOS=android matches "linux" and GOOS=illumos
matches "solaris". Only ios/arm64 is supported (ios/amd64 is
not).

GOOS=ios and GOOS=darwin remain essentially the same at this
point. They will diverge at later time, to differentiate macOS
and iOS.

Uses of GOOS=="darwin" are changed to (GOOS=="darwin" || GOOS=="ios"),
except if it clearly means macOS (e.g. GOOS=="darwin" && GOARCH=="amd64"),
it remains GOOS=="darwin".

Updates #38485.

debug/elf: support relocations relative to sections with non-zero addresses

2020-08-31T18:42:38+00:00

commit 72ec930fa70c20ce69b21bf32a7916c04c2e9c2f added basic support for
relocations, but assumed that the symbol value would be 0, likely because
.debug_info always has address == 0 in the ELF section headers.

CL 195679 added further support for relocations, but explicitly encoded
the original assumption that section addresses would be 0.

This change removes that assumption: all relocations will now be
properly computed based on the target symbol value even when that symbol
is a section with a non-zero address.

Typically, sections that are part of a LOAD program segment have
non-zero addresses. For example, .debug_ranges relocations could be
relative to .text, which usually has an address > 0.

Fixes #40879

Also reformat relocationTests slice to use indexed literals.

all: remove the nacl port (part 1)

2019-10-09T06:14:44+00:00

You were a useful port and you've served your purpose.
Thanks for all the play.

A subsequent CL will remove amd64p32 (including assembly files and
toolchain bits) and remaining bits. The amd64p32 removal will be
separated into its own CL in case we want to support the Linux x32 ABI
in the future and want our old amd64p32 support as a starting point.

debug/elf: perform stricter section header table checks in NewFile

2019-03-01T06:04:20+00:00

If an ELF file has no section header table (shoff = 0), shnum must be
zero as well according to elf(5).

So far, when only shnum was zero but shoff was non-zero (i.e. in an
invalid ELF file) shstrndx wasn't properly checked and could result in
an 'index out of range' later on.

all: skip unsupported tests on AIX

This commit skips tests which aren't yet supported on AIX.

nosplit.go is disabled because stackGuardMultiplier is increased for
syscalls.

all: skip unsupported tests for js/wasm

2018-04-30T19:39:18+00:00

The general policy for the current state of js/wasm is that it only
has to support tests that are also supported by nacl.

The test nilptr3.go makes assumptions about which nil checks can be
removed. Since WebAssembly does not signal on reading a null pointer,
all nil checks have to be explicit.
