Summary: error: EDGE_CROSSING missing across section boundary
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C code, derived from yesterday's linux-6.2-rc6:
enum { false, true };
__attribute__((__cold__)) _printk();
_static_cpu_has() {
asm goto("" : : : : t_yes, t_no);
t_yes:
return true;
t_no:
return false;
}
acpi_sleep_prepare() {
_Bool __trans_tmp_1 = _static_cpu_has();
if (!__trans_tmp_1)
acpi_set_waking_vector();
_printk();
}
does this:
$ /home/dcb36/gcc/results/bin/gcc -c -w -std=gnu11 -O2 bug878.c
bug878.c: In function ‘acpi_sleep_prepare’:
