b312fea191 The procedure to find an unused port for the debuginfod tests is susceptible to a TOCTOU failure. Change port finding in order to avoid this. Also use 'expect' to interact with the server process since we now use the server's output to determine whether a port is in use.
* binutils/testsuite/binutils-all/debuginfod.exp: Improve port

dc1e8a474f Indent labels
Labels don't go in the first column according to standard emacs C

bd0cf5a6ba RISC-V: Support the ISA-dependent CSR checking.
According to the riscv privilege spec, some CSR are only valid when rv32 or
the specific extension is set.  We extend the DECLARE_CSR and DECLARE_CSR_ALIAS
to record more informaton we need, and then check whether the CSR is valid
according to these information.  We report warning message when the CSR is
invalid, so we have a choice between error and warning by --fatal-warnings
option.  Also, a --no-warn/-W option is used to turn the warnings off, if
people don't want the warnings.

	whether or not this CSR is legal in the current ISA string.

	(init_opcode_hash): Update 'if (hash_error != NULL)' as hash_error is
	not a boolean.  This is same as riscv_init_csr_hash, so keep the

9f1528a1bd Merge changes from GCC for the config/ directory
GCC's config/ChangeLog since the last time this merge was done
(in the binutils-gdb commit 0b4d000cc4) is included at the
end of this commit message.

It is worth noting that the binutils-gdb commit 301a9420d9
added the file config/debuginfod.m4 which is not present in GCC's
config/ directory.  This file is preserved, unmodified, after this
commit.

In order to regenerate all of the configure files, I configured with
--enable-maintainer-mode, and built the 'all' target.  I then did the
same thing on a source tree without this patch, and only committed
those files that changed when this patch was added.

With the addition of section16 tests we have multiple tests

a8c4d40b57 ELF: Add support for unique section ID to assembler
Clang's integrated assembler supports multiple section with the same
name:

	.section .text,"ax",@progbits,unique,1
	nop
	.section .text,"ax",@progbits,unique,2
	nop

"unique,N" assigns the number, N, as the section ID, to a section.  The
valid values of the section ID are between 0 and 4294967295.  It can be
used to distinguish different sections with the same section name.

This is useful with -fno-unique-section-names -ffunction-sections.
-ffunction-sections by default generates .text.foo, .text.bar, etc.
Using the same string can save lots of space in .strtab.

This patch adds section_id to bfd_section and reuses the linker
internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler
internal use to mark valid section_id.  It also updates objdump to
compare section pointers if 2 sections comes from the same file since
2 different sections can have the same section name.

660df28acf Prefer object over notype symbols when disassembling
Changing objdump disassembly output like this always requires some
testsuite changes, with the avr and x64_64 changes simply due to
picking up better symbols, the whole point of the patch.

The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols
to STT_OBJECT, which objdump now chooses in preference to script
symbols.  The problem is that objdump looks at the first symbol in the
section being disassembled, and if object type, just dumps out bytes
rather than disassembling.  This results in new failures:

FAIL: JAL overflow 2
FAIL: undefined weak symbol overflow
FAIL: undefined weak symbol overflow (n32)
FAIL: undefined weak symbol overflow (n64)

So for mips-sgi-irix function symbols really do need to be function
type.  I fixed a few more than just the required minimum to avoid the
above test fails.

binutils/
	* objdump.c (compare_section): New static var.
	(compare_symbols): Sort by current section only.  Don't access
	symbol name out of bounds when checking for file symbols.
	Sort section symbols and object symbols.

	symbol test.
