Bug ID: 1423
Summary: Using -fno-strict-aliasing when compiling DPDK unit
tests reduces their effectiveness
Product: DPDK
Version: 23.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: eventdev
Assignee: dev@dpdk.org
Reporter: mattias.ronnb...@ericsson.com
Target Milestone: ---
6b89650418f adds
+# Strict-aliasing rules are violated by uint8_t[] to context size casts.
+CFLAGS += -fno-strict-aliasing
to app/test/meson.build.
This flag applies to all tests, not just the broken RTE graph tests (or SUT?).
Passing this flag to the compiler will prevent any functional tests (of any
component) from detecting any aliasing-related bugs found in code located in
SUT header files.
RTE graph should be fixed, rather than a whole-sale application of this
work-around to DPDK test suite.
In additional, reducing the level of compiler optimization will make the perf
test less relevant.
