Bug ID: 30383
Summary: [gdb/testsuite, -std=gnu90] FAIL:
gdb.opt/inline-locals.exp: info locals above bar 2
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: testsuite
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Using this patch and gcc 7.5.0 we have:
...
diff --git a/gdb/testsuite/gdb.opt/inline-locals.exp

index 3980f4ddd2a..60f62eca90d 100644

}
...
we have:
...
FAIL: gdb.opt/inline-locals.exp: info locals above bar 2
FAIL: gdb.opt/inline-locals.exp: info locals above bar 3
FAIL: gdb.opt/inline-locals.exp: print local 3
FAIL: gdb.opt/inline-locals.exp: scoped info locals at bp for locals 1
FAIL: gdb.opt/inline-locals.exp: scoped info locals at bp for locals 2
FAIL: gdb.opt/inline-locals.exp: scoped info locals at bp for locals 3
...
First sign of trouble is:
...
(gdb) PASS: gdb.opt/inline-locals.exp: func1 inlined 2
info locals^M
array = {0 <repeats 58 times>, 4195280, 0, -11296, 32767, 0, 0}^M
array = <optimized out>^M
(gdb) FAIL: gdb.opt/inline-locals.exp: info locals above bar 2
...
The problem seems to be that there's a difference of option about the address
of array:
...
(gdb) s
func1 (arg1=0) at /data/vries/gdb/src/gdb/testsuite/gdb.opt/inline-locals.c:43
43 init_array (array, 64);
(gdb) p &array
$1 = (int (*)[64]) 0x7fffffffda50
(gdb) s
init_array (array=0x7fffffffda30, n=64) at
/data/vries/gdb/src/gdb/testsuite/gdb.opt/inline-locals.c:36
36 for (i = 0; i < n; ++i)
...
Then with gcc 8.2.1:
...
FAIL: gdb.opt/inline-locals.exp: scoped info locals at bp for locals 1
FAIL: gdb.opt/inline-locals.exp: scoped info locals at bp for locals 2
...
and all clear with gcc 9.3.1.
