This fixes two minor problems with the new testcases. The first is
that almost all other tests, including all vec* tests, for powerpc use
names with dashes, not underscores. The more important one is the the
vec-rotate-1.c and vec-rotate-3.c tests need the -maltivec flag.

Hello,
The attached patch is a proposal to plug a hole in create_trace_edges
(dwarf2cfi.c), which doesn't handle casesi dispatch insns.
The visible misbehavior we observed is a failure in a cross configuration

GCC 9 optimizes a subset of expression of the form
(0 == strcmp(a, b)) based on the length and/or size of
the arguments but it doesn't take advantage of all
the opportunities there. For example in the following,
although it folds the first test to false it doesn't fold
the second one:
char a[4
PR target/91386 is a situation where a peephole2 pattern substitution
is discarded late because the selected instructions contain
frame-related notes that we cannot redistribute (because the pattern
has more than one insn in the output). Unfortunately, the original
insns were being modified durin
The addsi3_compare_op[12] patterns currently only have constraints to
pick the 32-bit variants of the instructions. Although the assembler
may sometimes opportunistically match a 16-bit t2 instruction, there's
no real control over that within the compiler. Consequently we might
emit a 32-bit

Hi.
The patch is about prevention of LTO section name clashing.
Now we have a situation where body of 2 functions is streamed
into the same ELF section. Then we'll end up with smashed data.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

In this PR we have two return paths from a function "map". The common
code sets to the value returned by one path, while the other
path does:
= map (&, ...);
We treated this call as tail recursion, losing the copy semantics
on the value returned by the recursive call.
