12 years agotile: support very large shared objects
Chris Metcalf [Mon, 5 Nov 2012 15:43:40 +0000 (10:43 -0500)]
tile: support very large shared objects

With gcc 4.8 tilegx has support for -mcmodel=large, to tolerate very
large shared objects.  This option changes the compiler output to
not include direct jump instructions, which have a range of only
2^30, i.e +/- 512MB.  Instead the compiler marshalls the target PCs
into registers and then uses jump- or call-to-register instructions.

For glibc, the upshot is that we need to arrange for a few functions
to tolerate the possibility of a large range between the PC and
the target.  In particular, the crti.S and start.S code needs
to be able to reach from .init to the PLT, as does gmon-start.c.
The elf-init.c code has the reverse problem, needing to call from
libc_nonshared.a (linked at the end of shared objects) back to the
_init section at the beginning.

No other functions in *_nonshared.a need to be built this way, as
they only call the PLT (or potentially each other), but all of that
code is linked at the very end of the shared object.

We don't build the standard -static archives with this option as the
performance cost is high enough and the use case is rare enough that
it doesn't seem worthwhile.  Instead, we would encourage developers
who need the -static model with huge executables to build a private
copy of glibc and configure it with -mcmodel=large.

Note that libc.so et al don't need any changes; the only changes
are for code that is statically linked into user code built with
-mcmodel=large.

For the assembly code, I just rewrote it so that it unconditionally
uses the large model.  To be able to pass -mcmodel=large to
csu/elf-init.c and csu/gmon-start.c, I need to check to see if the
compiler supports that flag, since gcc 4.7 doesn't; I added the
support by creating a small Makefile fragment that just runs the
compiler to check.

12 years agotile: improve simulator notification for relative paths in dlopen
Chris Metcalf [Fri, 2 Nov 2012 17:49:42 +0000 (13:49 -0400)]
tile: improve simulator notification for relative paths in dlopen

Normally, the simulator is notified of absolute pathnames by the
_dl_load_hook hook.  However, when a relative pathname is used, the
simulator may not know that the relative path matches a path that
it could figure out in the file system that it has access to.
Instead we provide a simplified version of the realpath function
so we can pass a plausible absolute pathname to the simulator.

Since we're now doing more work at object load time, we also add
a guard so we do no work at all if we're not running on the simulator.

- Fix bug in memcpy prefetch that caused us to never prefetch past
  the first cache line.
- Optimize misaligned memcpy by inlining _wordcopy_fwd_dest_aligned

- Make memcpy safe for forward copies by doing all the loads from
  a given cache line prior to doing a wh64 (cache line zero-fill)
  on the destination.  Remove now-redundant src == dst check.
- Copy and optimize the generic wordcopy.c routines to use the tile
  "double align" instruction instead of the MERGE macro; to avoid

[S390,PPC] Implement FUTEX_WAIT_BITSET for timedwait functions

Since the FUTEX_WAIT operation takes a relative timeout, the
pthread_cond_timedwait and other timed function implementations have
to get a relative timeout from the absolute timeout parameter it gets
before it makes the futex syscall.  This value is then converted back
into an absolute timeout within the kernel.  This is a waste and has
hence been improved upon by a FUTEX_WAIT_BITSET operation (OR'd with
FUTEX_CLOCK_REALTIME to make the kernel use the realtime clock instead
of the default monotonic clock).  This was implemented only in the x86
