I previously neglected to add address splitters for the io-variant

memory operands. In the examples I looked at, I found there was still
valid code coming out, but it seemed like an accident that it was

My series of patches from earlier this fall

This adds srodata section support to the RISC-V port, putting small read-only
data in the .srodata section instead of the .sdata section. There is already
code to put small read-only rtx in .srodata* instead of .rodata*. This
does the same for small read-only trees to be consistent.

So the underlying issue here is quite simple. Given something like

EVRP analysis will compute the resultant range using vrp_meet of the

James,
Here is a patch that will turn off the use of IFUNC and the LSE
instructions in libatomic if the compiler/assembler toolchain do not
understand the '-march=armv8-a+lse' option (changed from
-march=armv8.1-a). Rather than check the assembler directly, I used

it emits a library function call instead of emitting code for the 64 bit

This reverts the fix for PR67769 and installs an alternate fix
which is more targeted. This helps preserving range info where
important (int this case for emitting a -Wstringop-overflow

There's an unfortunate interaction between -save-temps=obj and
-fdump-tree- when subdirectories are in play.
Consider:
g++ -fdump-tree-all -save-temps=obj -c -o tgt/x.o sub/x.cc
we end up with a bunch of errors of the form:
sub/x.cc:1:0: error: could not open dump file
‘tgt/tgt/x.046t.profil
We limit the amount of copying for jump threading based on counting
stmts. This counting is overly pessimistic, because we will very
often delete stmts as a consequence of jump threading: when the final
conditional jump of a block is removed, earlier SSA names computed
exclusively for use in that
