Every generated inline probe function is wrapped with a
trivial caller that has a hard-coded condition test:
static inline void _nocheck__trace_test_wibble(void * context, int value)
{
tracepoint(qemu, test_wibble, context, value);
}
static inline void trace_test_wibble(void * context, int value)
{
if (true) {
_nocheck__trace_test_wibble(context, value);
}
}
This was introduced for TCG probes back in
864a2178: trace: [tcg] Do not generate TCG code to trace dynamically-disabled events
but is obsolete since
126d4123 tracing: excise the tcg related from tracetool
This commit removes the wrapping such that we have
static inline void trace_test_wibble(void * context, int value)
{
tracepoint(qemu, test_wibble, context, value);
}
The default build of qemu-system-x86_64 on Fedora with the
'log' backend, has its size reduced by 1 MB
