debug/elf: SPARC64 relocation type is only 8 bits

2016-11-10T22:58:49+00:00

https://docs.oracle.com/cd/E53394_01/html/E54813/chapter6-54839.html#OSLLGchapter6-24:

"For 64–bit SPARC Elf64_Rela structures, the r_info field is further
broken down into an 8–bit type identifier and a 24–bit type dependent
data field. For the existing relocation types, the data field is
zero. New relocation types, however, might make use of the data bits.

 #define ELF64_R_TYPE_ID(info)         (((Elf64_Xword)(info)<<56)>>56)
"

No test for this because the only test would be an invalid object file.

all: remove unnecessary type conversions

2016-04-15T07:31:45+00:00

cmd and runtime were handled separately, and I'm intentionally skipped
syscall. This is the rest of the standard library.

CL generated mechanically with github.com/mdempsky/unconvert.

debug/dwarf: add Reader.SeekPC and Data.Ranges

2016-03-22T14:06:09+00:00

These new methods help find the compilation unit to pass to the
LineReader method in order to find the line information for a PC.
The Ranges method also helps identify the specific function for a PC,
needed to determine the function name.

This uses the .debug.ranges section if necessary, and changes the object
file format packages to pass in the section contents if available.

all: make copyright headers consistent with one space after period

2016-03-01T23:34:33+00:00

This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.

Go policy has been single space after periods in comments for some time.

The copyright header template at:

    https://golang.org/doc/contribute.html#copyright

also uses a single space.

Make them all consistent.

debug/elf: transparently decompress compressed sections

2015-12-03T20:53:11+00:00

This adds support for compressed ELF sections. This compression is
treated as a framing issue and hence the package APIs all
transparently decompress compressed sections. This requires some
subtlety for (*Section).Open, which returns an io.ReadSeeker: since
the decompressed data comes from an io.Reader, this commit introduces
a Reader-to-ReadSeeker adapter that is efficient for common uses of
Seek and does what it can otherwise.

Fixes #11773.

dwbug/elf: support old-style compressed DWARF

2015-12-03T20:53:04+00:00

GCC and LLVM support zlib-compressing DWARF debug sections (and
there's some evidence that this may be happening by default in some
circumstances now).

Add support for reading compressed DWARF sections. Since ELF
relocations apply to the decompressed data, decompression is done
before applying relocations. Since relcations are applied by
debug/elf, decompression must also be handled there.

Note that this is different from compressed ELF sections, which is a
more general mechanism used by very recent versions of GCC.

Updates #11773.
