Bug ID: 89234
Summary: ICE in get_eh_region_and_lp_from_rtx at
gcc/except.c:1824
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: segher at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: ppc64le-linux-gnu, ppc64-linux-gnu
Following is causing ICE:
$ cat ice.ii
typedef float a __attribute__((mode(SD)));
a *b;
a c;
void d() { *b = c + 01.5; }
$ ppc64-linux-gnu-g++ ice.ii -c -fnon-call-exceptions -O2 -fsanitize=null
-fdump-tree-original=/dev/stdout
;; Function void d() (null)
;; enabled by -tree-original
<<cleanup_point <<< Unknown tree: expr_stmt
(void) (*b = (a) ((double) c + 1.5e+0)) >>>>>;
during RTL pass: reload
ice.ii: In function ‘void d()’:
ice.ii:4:27: internal compiler error: Segmentation fault
4 | void d() { *b = c + 01.5; }
