Bug ID: 19236
Summary: NULL global variable breakage
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
Assignee: systemtap at sourceware dot org
Reporter: mcermak at redhat dot com
CC: jistone at redhat dot com
Target Milestone: ---
Created attachment 8779
--> https://sourceware.org/bugzilla/attachment.cgi?id=8779&action=edit
proposed patch
One private feature related thing I didn't notice earlier is following failure
of the null buildok testcase:
=======
# stap -e 'probe begin { println(NULL) }' |& head
In file included from include/linux/module.h:17:0,
from /usr/local/share/systemtap/runtime/linux/runtime.h:14,
from /usr/local/share/systemtap/runtime/runtime.h:24,
from
/tmp/stapZoovRF/stap_f8cdd473c043e55c42c181392132b9c4_903_src.c:25:
include/linux/moduleparam.h:338:22: error: pasting "__check_" and "(" does not
give a valid preprocessing token
static inline type *__check_##name(void) { return(p); }
^
/usr/local/share/systemtap/runtime/linux/runtime.h:276:38: note: in expansion
of macro ‘__param_check’
#define param_check_int64_t(name, p) __param_check(name, p, int64_t)
^
#
=======
Bisecting the source shows it's related to commit
6b15a04af5b6904c750c1878a965032a906c4874. Looking at the very end of the -p3
output I see this:
=======
# stap -p3 -e 'probe begin { println(NULL) }' |& tail -n 2
#undef __global_NULL
module_param_named (NULL, global(s___global_NULL), int64_t, 0);
#
=======
Attached patch fixes the issue for me.
