Bug ID: 27129
Summary: [aarch64] broken logical immediate operations in
NDEBUG builds
Product: binutils
Version: 2.36 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: d_garry at mail dot ru
Target Milestone: ---
When -NDEBUG is defined during build, it transforms "assert(anything)" into
something like "(void*)(0)" - at least in Linux, as defined in <assert.h>:
ifdef NDEBUG
...
# define assert(expr) (__ASSERT_VOID_CAST (0))
...
endif
Thus in case when any function is about to be called from assert, it will be
silently ignored. Example (see opcodes/aarch64-asm.c:555):
/* The constraint check should have guaranteed this wouldn't happen. */
assert (aarch64_logical_immediate_p (imm, esize, &value));
If -NDEBUG-ged, aarch64_logical_immediate_p() simply won't be called, making
aarch64 logical operations (e.g. AND opcode) work incorrectly.
Seems that regression occured in commit 535b785fb0.
