The patch implements support for omp_low_lat_mem_space and
omp_low_lat_mem_alloc on NVPTX offload devices. The omp
The patch is about small refactoring of the plugin.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

include/ChangeLog:
* plugin-api.h (enum ld_plugin_tag): Do not set implicit enum
values.
lto-plugin/ChangeLog:
This makes sure to detect overflow when computing DR_GROUP_GAP
and DR_GROUP_SIZE more thoroughly so artificial testcases like the
added one are not fooling the existing check.
Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

Hi!
For ADDR_EXPR gimple_debug_bind_get_value fold_stmt_1 uses
maybe_canonicalize_mem_ref_addr earlier and I think that should
resolve the concerns raised in PR52329. But folding ADDR_EXPR

Yup, GCC does simplify it that way in the end, so I didn't really bother to
simplify it here. That said, I'm open to simplifying it here as well, but

Shouldn't that use { dg-require-effective-target sse2 }?

Hi!
The testcase uses SSE and SSE2 intrinsics, so fails on i686-linux
if -msse2 isn't enabled by default. Fixed by adding -msse2 to
dg-options.
Bootstrapped/regtested on x86_64-linux and i686-linux, committed to
trunk as obvious.
