Hi!
The PR38359 change made the -1 >> x to -1 optimization less useful by
requiring that the x must be non-negative.
Shifts by negative amount are UB, but we for historic reasons had in some
(but not all) places some hack to treat shifts by negative value as the

This properly skips debug USE_STMTs when looking for non-SLP sinks.

Hi,
tree-streamer-in currently calls init_tree_ssa that calls init_ssanames
that allocates space in ssa_names array for 50 names. Later it streams
in the count and calls init_tree_ssa again, this time with correct
count, which is rounded up to 50 and allocated again leaking the first
array.

Some tests force -mcpu=cortex-mXX but do not add -mthumb, causing
errors if GCC is not configured to default to Thumb code
(--with-mode=thumb):
cc1: error: target CPU does not support ARM mode
This patch adds -mthumb where relevant.

Hi,
I adjusted some vectorization test cases for vect_partial_vectors_usage_1
before, but as exposed in the recent testings, some of them need to be
adjusted again. The reason is that the commit r11-3393 improved the
