When running test-case gdb.threads/attach-many-short-lived-threads.exp with
check-read1, I ran into:
...
FAIL: gdb.threads/attach-many-short-lived-threads.exp: iter 1: \
no new threads (timeout)
...
Fix this by rewriting the gdb_test_multiple call using -lbl and exp_continue.
Tested on x86_64-linux, with make targets check and check-read1.

In git commit fd486f32d1 I put some static variables used by
get_symbol_for_build_attribute in a file scope ba_cache struct. This
was to prevent leaks in get_symbol_for_build_attribute, and to tidy up
before readelf exited. The patch wasn't quite right though. When
readelf processes more than one file it was possible to double free
arrays allocated in get_symbol_for_build_attribute.
* readelf.c (process_file): Clean ba_cache.
When running testcase gdb.cp/step-and-next-inline.exp, I get:
...

# of untested testcases 2
...
Fix this by using a new gdb_caching_proc supports_statement_frontiers.
Tested on x86_64-linux, with gcc 7.5.0 (which does not support
-gstatement-frontiers) and with gcc 8.4.0 (which does support
-gstatement-frontiers).
gdb/testsuite/ChangeLog:

With test-case gdb.base/printcmds.exp, I run into:
...
(gdb) print teststring2^M
$563 = (charptr) "more contents"^M
(gdb) FAIL: gdb.base/printcmds.exp: print teststring2
...
The corresponding test is:
...
gdb_test "print teststring2" " = (charptr) \"more contents\""
...
Fix the FAIL by adding the missing quoting for the parentheses around charptr.
Tested on x86_64-linux.

* gdb.base/printcmds.exp: Add missing quoting for "print
teststring2".
This test XPASSes on the generic ELF targets, so adjusting. I also
made xtensa an xfail instead of a skip, since skip is hiding some
nastiness.
* testsuite/ld-elf/non-contiguous.d: Don't xfail generic ELF
targets. Don't skip xtensa, xfail instead.
After the ld non-contiguous memory support my regen of bfd-in2.h
didn't match exactly what was committed, so I took the opportunity to
line up all the comments.
* section.c (BFD_FAKE_SECTIONS): Formatting.
* bfd-in2.h: Regenerate.
This changes the extension language pretty-printers to use the value
API.
Note that new functions were needed, for both Guile and Python.
Currently both languages always wrap values by removing the values
from the value chain. This makes sense to avoid strange behavior with
watchpoints, and to avoid excessive memory use. However, when
printing, it's important to leave the passed-in value untouched, in
case pretty-printing does nothing -- that way the caller can still
access it.
