f35d6971cd gdb/testsuite: make test names unique in gdb.python/py-finish-breakpoint.exp
Make test names unique by just adding additional text to the test
names.  As this is a Python test that repeatedly imports the Python
script I've just numbered the test names in this case rather than
trying to come up with anything better, hence we have:

  import python scripts, 1
  import python scripts, 2
  ...
  import python scripts, 6

Not great, but hopefully good enough.  Everything else has a slightly
more descriptive test name.

1b2cb8e2ee aix: implement TLS relocation for gas and ld
Add support for TLS in XCOFF. Amongst the things done by this commit:
 - Update XCOFF auxialiary header to match new version and allow TLS
   sections.
 - Add TLS sections (.tdata and .tbss) support in gas and ld.
 - Add support for the TLS relocations in gas and ld.
   Two different types BFD_RELOC are created for PPC and PPC64 as
   the size is a pointer, thus distinct in 32 or 64bit.

The addresses given by ld to .tdata and .tbss is a bit special. In
XCOFF, these addresses are actually offsets from the TLS pointer
computed at runtime. AIX assembly and linker does the same. In
top of that, the .tdata must be before .data (this is mandatory for AIX
loader). Thus, the aix ld script is recomputing "." before .data to restore
its original value. There might be a simpler way, but this one is working.

Optimisation linked to TLS relocations aren't yet implemented.

4a403be0c1 aix: implement R_TOCU and R_TOCL relocations
Implement support for largetoc on XCOFF.
R_TOCU and R_TOCL are referenced by the new BFD defines:
BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO.
A new toc storage class is added XMC_TE.

In order to correctly handle R_TOCU, the logic behind
xcoff_reloc_type_toc is changed to compute the whole TOC offset
instead of just the difference between the "link" offset and the
"assembly" offset.

In gas, add a function to transform addis format used by AIX
"addis RT, D(RA)" into the ELF format "addis RT, RA, SI".

2c1bef53de aix: correct HOWTO table and add missing relocations
Since the last time AIX HOWTO table was modified, IBM has now
released an official documentation about XCOFF relocations.
This commit corrects the wrong ones and add some missing.
For now, the "custom" relocations made for xcoff_rtype2howto have
been kept.
The new relocations are still set as EMPTY_HOWTO because they will
be implemented in later commits.

In xcoff[64]_ppc_relocate_section, instead of recreating howto
from scratch, it's better to use the existing howto from the
table and fixing it according to r_size field.

ebdcad3fdd RISC-V: Improve multiple relax passes problem.
According to the commit abd20cb637, an
intersting thing is that - the more relax passes, the more chances of
relaxations are reduced [1].  Originally, we set the boolean `again`
to TRUE once the code is actually deleted, and then we run the relaxations
repeatedly if `again` is still TRUE.  But `again` only works for the
relax pass itself, and won't affect others.  That is - we can not use
`again` to re-run the relax pass when we already enter into the following
passes (can not run the relax passes backwards).  Besides, we must seperate
the PCREL relaxations into two relax passes for some reasons [2], it make
us lose some relax opportunities.

This patch try to fix the problem, and the basic idea was come from Jim
Wilson - we use a new boolean, restart_relax, to determine if we need to
run the whole relax passes again from 0 to 2.  Once we have deleted the
code between relax pass 0 to 2, the restart_relax will be set to TRUE,
we should run the whole relaxations again to give them more chances to
shorten the code.  We will only enter into the relax pass 3 when the
restart_relax is FALSE, since we can't relax anything else once we start
to handle the alignments.

I have passed the gcc/binutils regressions by riscv-gnu-toolchain, and
looks fine for now.

"0f" involved there anywhere) infixes where the respective enum gets

319419837c x86: correct decoding of nop/reserved space (0f18 ... 0x1f)
All encodings not used in this range are (reserved) NOPs. Hence their
decoding should be fully consistent. For this to work the PREFIX_IGNORED
logic needs slightly extending, such that the attribute will also
- have an effect when used inside prefix_table[], yet without always
  falling back to using slot 0,
- cause prefixes marked as ignored while decoding through prefix_table[]
  to no longer be considered decoded, when encountered in a subsequent
  decoding step.

In adjacent code also drop meaningless PREFIX_OPCODE.

67b0f68480 bfd: strip symbols not representable in COFF/PE symbol table
The offset-within-section field in the symbol table entry is only 32
bits wide, so rather than emitting bogus entries omit them, and issue
a diagnostic identifying the issue.

This requires adjusting the PR/22267 test to no longer produce symbols
with out of range values on 64-bit BFD. This also depends on
adjustments to testsuite/ld-scripts/map-address.* made by an earlier
patch. The purpose of the test can very well be achieved nevertheless.

ccdc02ed07 Fix function call regression in new evaluator
The internal AdaCore test suite revealed a bug in the new evaluator.
A hunk of evaluate_funcall was not correctly transcribed.  This was
not caught in my original testing because the feature in question was
apparently not tested in gdb.

This patch fixes the oversight.  The idea here is that ordinary
function calls should use the function's formal parameter types as the
expected types of subexpressions.

Regression tested on x86-64 Fedora 32.

5dc75cf325 ld: adjust PE base relocations testcase
mcore-pe and sh-pe pointed out that the testcase added by 6fa7408d72
("ld: don't generate base relocations in PE output for absolute
symbols") wasn't quite generic enough yet. Copy entry point stuff from
another test and increase alignment to also cover targets with a page
size lower than 4k.

Despite all of this the test needs to be xfail-ed for mcore, as this
target isn't included in the set getting DLL_SUPPORT enabled in
emultempl/pe.em, and hence no base relocations get generated there
(yet).

fbb1aaceba gdb: fix field names of GDB's type main_type structure
In commit:

  commit 5b7d941b90
  Date:   Fri Jan 22 12:21:09 2021 -0500

      gdb: add owner-related methods to struct type

two fields of struct maint_type were renamed.  'flag_objfile_owned'
became 'm_flag_objfile_owned' and 'owner' became 'm_owner'.  Update
our python helper script to take this into account.

I've added a basic test that uses the self-test framework to load the
pretty printers, and print a type.

The test relies on stopping in GDB's `value_print` function.

gdb/ChangeLog:

	* gdb-gdb.py.in (StructMainTypePrettyPrinter) <owner_to_string>:
	Updated fields names flag_objfile_owned to m_flag_objfile_owned,
	and owner to m_owner.

	* gdb.gdb/python-helper.exp: New file.

7ba155b370 gdb/fortran: add support for 'SIZE' keyword
Add support for the 'SIZE' keyword to the Fortran expression parser.
This returns the number of elements either in an entire array (passing
a single argument to SIZE), or in a particular dimension of an
array (passing two arguments to SIZE).

At this point I have not added support for the optional third argument
to SIZE, which controls the exact integer type of the result.

742732c7f0 x86: fold some prefix related attributes into a single one
RepPrefixOk, HLEPrefixOk, and NoTrackPrefixOk can't be specified
together, so can share an enum-like field. IsLockable can be inferred
from HLE setting and hence only needs specifying when neither of them

e93a3b27b2 x86-64: make SYSEXIT handling similar to SYSRET's
Despite SYSEXIT being an Intel-only insn in long mode, its behavior
there is similar to SYSRET's: Depending on REX.W execution continues in
either 64-bit or compatibility mode. Hence distinguishing by suffix is
as necessary here as it is there.

87fa7d568d bfd: don't silently wrap or truncate PE image section RVAs
In PE images section addresses get expressed as addresses relative to
the image base. Therefore the VA of a section must be no less than the
image base, and after subtraction of the image base the resulting value
should fit in 32 bits. (The issue is particularly obvious to notice when
sections, perhaps because of ELF assumptions, get placed at VA 0 by
default. Debugging info sections as well as .comment, when input files
are ELF, are a good example. All such sections need proper mentioning in
the linker script to avoid this warning.)

There are a number of test cases which previously produced bogus images,
yet still declared the test a success. Like done for other tests
already, force a zero image base for these. This then also allows (and
requires) dropping again xfail-s which 39a7b38fac ("Fix linker tests
to work with 16-bit targets") had added to ld-scripts/default-script*.d
(originally as skip-s). This also depends on similar adjustments to
testsuite/ld-scripts/map-address.* made by an earlier patch.

For ld-scripts/print-memory-usage.* I suppose xcoff could be dropped
from the exclusion list by suppressing garbage collection, just like
already done in e.g. (as seen in the diff here) ld-scripts/data.*, but I
didn't want to make unrelated adjustments.

8c379db285 Enable maintainer mode for sim
The sim's recently switch to using Automake caused a build failure for
me, because I didn't have the correct auto* tools in my path.
However, the rule in the tree is that this is not needed in general.
This patch adds a call to AM_MAINTAINER_MODE, to align the sim with
the way the rest of the tree works here.
