4 years agoChange regcache list to be an hash map
Simon Marchi [Wed, 8 Jan 2020 16:39:29 +0000 (11:39 -0500)] 
Change regcache list to be an hash map

The regcache objects created for threads are stored in a linked list,
regcache::current_regcache.

This may result in bad performance when debugging a lot of threads, as GDB
needs to walk the linked list to fetch a regcache given a ptid.

This patch replaces the linked list with an std::unordered_map, indexed by
(ptid, arch).  The lookups, in get_thread_arch_aspace_regcache, should become
faster when the number of threads grow.  With a small number of threads, it
will probably be a bit slower to do an hash map lookup than to walk a few
linked list nodes,  but it should not be perceptible.

The function registers_changed_ptid deletes all regcaches related to a given
ptid (there could be multiple, with different arches).  Since the hash map is
indexed by (ptid, arch), we can't do a simple lookup, so we fall back on
iterating on all the hash map values.  It should be the same complexity as what
we have today.  This function is called when resuming execution, so it would be
nice to find a more efficient way to do this.

Similarly, the function regcache_thread_ptid_changed is called when a thread
changes ptid, so it needs to look up all regcaches for a given ptid.  This one
also iterates on all the hash map values.  However, it is not called often
(mostly when creating an inferior, on some specific platforms), so it shouldn't
be a problem.

libctf: compilation failure on MinGW due to missing errno values

This commit fixes a compilation failure in a couple of libctf files
due to the use of EOVERFLOW and ENOTSUP, which are not defined
when compiling on MinGW.

libctf/ChangeLog:

PR binutils/25155:
* ctf-create.c (EOVERFLOW): If not defined by system header,
redirect to ERANGE as a poor man's substitute.
* ctf-subr.c (ENOTSUP): If not defined, use ENOSYS instead.

This one is how Eli implemented it. I think this implementation
has a weakness in the following sense: If other units in libctf
start using those constants, we'll get the same error again.
Also, I'm wondering whether their use is documented as part of
the official libtcf API or not -- users might be writing code
that tests for these, and if the system doesn't support them,
how would they know what errno code to use in its place. This
argues for a having that information in one of libctf's header
files. I think it would be nice to have those in ctf-decls.h,
but I think we'll need to include <errno.h> in ctf-decls.h if
we decide to define those macros there.

Rather than second-guess what the CTF developers would prefer,
I'm starting by sending Eli's patch, to see what you guys think.

Thanks,
