Dear all,
this small patch fixes some small issues with the current FINAL
implementation, which is still disabled. Namely:
(a) class.c: TRANSFER has an optional size= argument; if one doesn't has
an actual-argument (which can be expr == NULL), it segfaults.
(b) class.c: SIZE needs to return a

It doesn't make sense. memcpy from NULL src pointer?

Basic-block vectorization "removes" scalar stmt calls (well, replaces them
with assignment from zero) even if the scalar result is used from
non-vectorized code (yes, that's a cost issue as well, I filed
PR56612 for this).
The following is an easy workaround - while DCE is not run for

This uses bitmap_heads for more bitmaps (one indirection less
and slightly smaller memory footprint) and it avoids the
extra indirection to avoid having a vec of a vec which is now
possible.

This changes the vector of locations we track for each memory reference
from storing a pointer to a location aggregate to storing the aggregate
directly, avoiding an indirection and tons of small memory allocations.
This also touches the way we iterate over locations of refs - instead
of building
This makes the linked list of dependent stmts a vector instead.
Saves separate allocation / free of list entries and overall
some memory (overhead for vecs is less than 50%).

This patch (suggested by Steven B) removes some redundant loop
assertions that are currently being missed, resulting in redundant
branches appearing prior to many loops on powerpc64. Bootstrapped and
tested with no new regressions on powerpc64-unknown-linux-gnu. Ok for
trunk?
Thanks,

Hi!
This patch is an attempt to warn about undefined behavior in simple loops
with known constant number of latch executions, which probably is the most
common case where gcc 4.8 started to turn finite loops involving undefined
behavior before reaching last iteration into endless loops.

This patch adds an initial implementation for a new helper type for
generating GIMPLE statements.
The type is called gimple_builder. There are two main variants:
gimple_builder_normal and gimple_builder_ssa. The difference between
the two is the temporaries they create. The 'normal' builder cre

Great. I was just asking you about this on IRC - you not there - but

Nice -- GCC LOC will be significantly reduced with these interfaces.
Using 'add' as interface name can be confusing -- new, or new_stmt, or
new_assignment/new_call etc might be better -- but we can delay the
bike shedding later.
