Subject: [PATCH] fixup! commands: ubsan: hide zero division in test
Date: Wed, 19 Mar 2025 17:10:56 +0100 [thread overview]
Message-ID: <20250319161056.2086121-1-a.fatoum@pengutronix.de> (raw)
GCC complains that we pass the address of the variable instead of the
variable itself:
commands/ubsan.c: In function ‘test_ubsan_divrem_overflow’:
error: lvalue required in ‘asm’ statement
63 | __asm__ ("" : "=r" (var) : "0" (var))
| ^~~~~~~
./commands/ubsan.c:46:9: note: in expansion of macro ‘OPTIMIZER_HIDE_VAR’
46 | OPTIMIZER_HIDE_VAR(&val2);
