Bug ID: 118772
Summary: BPF doesn't actually support effective-target
'exceptions'?
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: jemarch at gcc dot gnu.org
Target Milestone: ---
Target: BPF
Working on GCN, nvptx targets, I find that a few GCC test cases are incorrectly
tagged as requiring effective-target 'nonlocal_goto', when in fact they should
require effective-target 'exceptions', and I'd like to fix this up in the
affected test cases. However: while BPF currently isn't effective-target
'nonlocal_goto' (correct, per my understanding), but it claims to support
effective-target 'exceptions' (wrong, per my understanding). (For example, "In
eBPF it is not possible to unwind frames." comments in 'gcc/config/bpf/bpf.h',
'gcc/config/bpf/bpf.cc'.) If you ACK, to avoid regressing the to-be-fixed test
cases for BPF, I'll add '[istarget bpf-*-*]' to the 'return 0' branch in
'gcc/testsuite/lib/target-supports.exp:check_effective_target_exceptions'.
(Likewise for nvptx...)
