Jim Wilson c6261a00c3 RISC-V: Fix ld relax failure with calls and align directives.
Make _bfd_riscv_relax_call handle section alignment padding same as
the _bfd_riscv_relax_lui and _bfd_riscv_relax_pc functions already
do.  Use the max section alignment if section boundaries are crossed,
otherwise the alignment of the containing section.

	bfd/
	PR 25181
	* elfnn-riscv.c (_bfd_riscv_relax_call): Always add max_alignment to
	foff.  If sym_sec->output_section and sec->output_section are the same
	and not *ABS* then set max_alignment to that section's alignment.

	ld/
	PR 25181
	* testsuite/ld-riscv-elf/call-relax-0.s: New file.
	* testsuite/ld-riscv-elf/call-relax-1.s: New file.
	* testsuite/ld-riscv-elf/call-relax-2.s: New file.
	* testsuite/ld-riscv-elf/call-relax-3.s: New file.
	* testsuite/ld-riscv-elf/call-relax.d: New test.
	* testsuite/ld-riscv-elf/ld-riscv-elf.exp: Run call-relax test.

		README for LD

This is the GNU linker.  It is distributed with other "binary
utilities" which should be in ../binutils.  See ../binutils/README for
more general notes, including where to send bug reports.

There are many features of the linker:

* The linker uses a Binary File Descriptor library (../bfd)
  that it uses to read and write object files.  This helps
  insulate the linker itself from the format of object files.

* The linker supports a number of different object file
  formats.  It can even handle multiple formats at once:
  Read two input formats and write a third.

* The linker can be configured for cross-linking.

* The linker supports a control language.

* There is a user manual (ld.texi), as well as the
  beginnings of an internals manual (ldint.texi).

Installation
============

See ../binutils/README.

If you want to make a cross-linker, you may want to specify
a different search path of -lfoo libraries than the default.
You can do this by setting the LIB_PATH variable in ./Makefile
or using the --with-lib-path configure switch.

To build just the linker, make the target all-ld from the top level
directory (one directory above this one).

Porting to a new target
=======================

See the ldint.texi manual.

Reporting bugs etc
===========================

See ../binutils/README.

Known problems
==============

The Solaris linker normally exports all dynamic symbols from an
executable.  The GNU linker does not do this by default.  This is
because the GNU linker tries to present the same interface for all
similar targets (in this case, all native ELF targets).  This does not
matter for normal programs, but it can make a difference for programs
which try to dlopen an executable, such as PERL or Tcl.  You can make
the GNU linker export all dynamic symbols with the -E or
--export-dynamic command line option.

HP/UX 9.01 has a shell bug that causes the linker scripts to be
generated incorrectly.  The symptom of this appears to be "fatal error
- scanner input buffer overflow" error messages.  There are various
workarounds to this:
  * Build and install bash, and build with "make SHELL=bash".
  * Update to a version of HP/UX with a working shell (e.g., 9.05).
  * Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in
    genscripts.sh with "sh ${srcdir}..." (no parens) and make sure the
    emulparams script used exports any shell variables it sets.
