[Bug target/87231] stdatomic.h: No such file or directory on OpenBSD 6.3
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87231 --- Comment #3 from Shane Kerr --- (In reply to Andrew Pinski from comment #2) > Similar issue to PR 69744. OpenBSD config should just remove that. How would I do that? Should I just comment out the USER_H variable?

[Bug bootstrap/87225] New: tree-vect-stmts.c:3748 error: converting to 'bool' from 'std::nullptr_t' requires direct-initialization [-fpermissive]
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87225
Bug ID: 87225
Summary: tree-vect-stmts.c:3748 error: converting to 'bool'
from 'std::nullptr_t' requires direct-initialization
[-fpermissive]
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: sh...@time-travellers.org
Target Milestone: ---
The vectorizable_simd_clone_call() function returns a bool, but one return has
NULL which the compiler complains on, breaking the build.
The function declaration:
static bool
vectorizable_simd_clone_call (gimple *stmt, gimple_stmt_iterator *gsi,
gimple **vec_stmt, slp_tree slp_node)
{
The return in question:
unsigned HOST_WIDE_INT vf;
if (!LOOP_VINFO_VECT_FACTOR (loop_vinfo).is_constant ())
{
if (dump_enabled_p ())
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not considering SIMD clones; not yet supported"
" for variable-width vectors.\n");
return NULL;
}
The error message:
In file included from
/home/shane/gcc-8.2.0/host-i386-unknown-openbsd6.3/prev-gcc/include-fixed/stddef.h:48,
from ../.././gcc/system.h:43,

../.././gcc/tree-vect-stmts.c: In function 'bool
vectorizable_simd_clone_call(gimple*, gimple_stmt_iterator*, gimple**,
slp_tree)':
../.././gcc/tree-vect-stmts.c:3748:14: error: converting to 'bool' from
'std::nullptr_t' requires direct-initialization [-fpermissive]
return NULL;
^~~~
This is on OpenBSD 6.3. My build process is:
* Install OpenBSD (all defaults).
* Run syspatch
* Install packages:
# pkg_add wget
# pkg_add gmp mpfr libmpc
# pkg_add gmake
* Get latest source and unpack:
$ wget
ftp://ftp.nluug.nl/mirror/languages/gcc/releases/gcc-8.2.0/gcc-8.2.0.tar.gz
$ tar xzf gcc-8.2.0.tar.gz
$ cd gcc-8.2.0
* Build:
$ ./configure --prefix=/opt/gcc-8.2.0 --with-gmp=/usr/local
--enable-languages=c,c++
$ gmake
It fails in stage2:
$ cat stage_current
stage2
I am curious how this build ever works at all on any system!
