    • Update file position for inquire lazily. · 08810e52 
      libgfortran ChangeLog:

2011-10-31  Janne Blomqvist  <jb@gcc.gnu.org>

	* io/inquire.c (inquire_via_unit): Check whether we're at the
	beginning or end if the position is unspecified. If the position
	is not one of the 3 standard ones, return unspecified.
	* io/io.h (update_position): Remove prototype.
	* io/transfer.c (next_record): Set the position to unspecified,
	letting inquire figure it out more exactly when needed.

    • Use more efficient alignment in ggc · 3bc50163

ggc-page, which use a hardware division instructions currently.

exploits that pages are a power of two.

    • Add a fragmentation fallback in ggc-page v2 · 25f0ea81 
      There were some concerns that the earlier munmap patch could lead
to address space being freed that cannot be allocated again
by ggc due to fragmentation. This patch adds a fragmentation
fallback to solve this: when a GGC_QUIRE_SIZE sized allocation fails,
try again with a page sized allocation.

Passes bootstrap and testing on x86_64-linux with the fallback
forced artificially.

v2: fix missed initialization bug added in last minute edit.

    • Free large chunks in ggc v2 · d33ef9a5 
      This implements the freeing back of large chunks in the ggc madvise path
Richard Guenther asked for.  This way on systems with limited
address space malloc() and other allocators still have
a chance to get back at some of the memory ggc freed. The
fragmented pages are still just given back, but the address space
stays allocated.

I tried freeing only aligned 2MB areas to optimize for 2MB huge
pages, but the hit rate was quite low, so I switched to 1MB+
unaligned areas.

v2: Hardcode free unit size instead of param

2011-10-18  Andi Kleen  <ak@linux.intel.com>

	* ggc-page (release_pages): First free large continuous
	chunks in the madvise path.

    • Add missing page rounding of a page_entry · bf72b009 
      This one place in ggc forgot to round page_entry->bytes to the
next page boundary, which lead to all the heuristics in freeing to
check for continuous memory failing. Round here too, like all other
allocators already do. The memory consumed should be the same
for MMAP because the kernel would round anyways. It may slightly
increase memory usage when malloc groups are used.

This will also increase the hitrate on the free page list
slightly.
