Currently, when `mips_elf_calculate_relocation' is asked to relocate an
undefined symbol, it reports an error or a warning and immediately
returns without performing the relocation. This is fine if the link
fails, but if unresolved_syms_in_objects == RM_GENERATE_WARNING, the
link will continue and output some unrelocated code, which is a
regression from commit e7e2196da3f0 ("MIPS/BFD: Correctly report
undefined relocations").
Fix this by continuing after calling the `undefined_symbol' hook unless
this is an error condition.

translate_symbol_table returns false on detecting an out of range name
string offset, hooray for error checking, but doesn't set bfd_error or
print a useful error. bfd_error therefore contains whatever it had
previously, in my testing, bfd_error_system_call. So the error
printed depended on errno.

This patch adds --enable-separate-code to ld configure to turn on
-z separate-code by default and enables it by default for Linux/x86.
This avoids mixing code pages with data to improve cache performance
as well as security.
To reduce x86-64 executable and shared object sizes, the maximum page
size is reduced from 2MB to 4KB when -z separate-code is turned on by
default. Note: -z max-page-size= can be used to set the maximum page
size.
We compared SPEC CPU 2017 performance before and after this change on
Skylake server. There are no any significant performance changes.
Everything is mostly below +/-1%.

More standarization of error/warning messages. The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop. I've replaced the line breaks with
semicolons.
So for instance the following
system/path/to/ld: myobject.o: invalid special symbol `foo'.
system/path/to/ld: It must be a global or weak function symbol.
becomes
system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol

The GNU coding standard says error messages should be of the form
program:sourcefile:lineno: message
or
program: message
and
"The string message should not begin with a capital letter when it
follows a program name and/or file name, because that isn’t the
beginning of a sentence. (The sentence conceptually starts at the
beginning of the line.) Also, it should not end with a period."
This patch does that for ppc, and removes some British spelling.
I've also switched some error output from using the linker callback
einfo to _bfd_error_handler, due to improved compilation time
argument checking now done for the latter function.

|

Use the SEC_FIXED_SIZE flag to actually fix the size of `.reginfo' and
`.MIPS.abiflags' sections in `_bfd_mips_elf_always_size_sections', as
originally intended, removing link failures such as:
ld: final link failed: Section has no contents
or:
ld: final link failed: Bad value
or:
ld: foo: .reginfo section size should be 24 bytes, actual size is 32
and assertion failures like:
ld: BFD (GNU Binutils) 2.30.51.20180131 assertion fail .../bfd/elfxx-mips.c:14322
in link scenarios involving a linker script that either creates an
output `.reginfo' or `.MIPS.abiflags' section from scratch or produces
either section from different sections. If such an output section's
size turns out to be incorrect according to the psABI, then the section
is either truncated or padded out to the correct size, as relevant.
This allows people to handle these sections in a link in an unusual way,
while still addressing the issue covered by commit 58807c48a5a3
("_bfd_mips_elf_final_link: Notify user about wrong .reginfo size").
The original arrangement, coming from an unindentified change made to
what was called `mips_elf_always_size_sections' back then, between
commit 02650bd0a97e ("This adds ABI flags to MIPS/ELF object files.")
and commit 252b5132c753 ("19990502 sourceware import"), also missing
from BFD ChangeLog files, assumed that the output section size is not
going to change after return from `bfd_elf_size_dynamic_sections', the
caller of that function, called in turn from `ldemul_before_allocation'
via `gld${EMULATION_NAME}_before_allocation' in ld/emultempl/elf32.em,
and ultimately from `lang_process'. This is because later on in
`lang_process' processing `lang_size_sections' is called , happily
recalculating the section size, and it has actually already been the
case at the time of commit 252b5132c753 ("19990502 sourceware import"),
so the assumption was clearly incorrect right from the beginning.
