Bug ID: 15552
Summary: macro error messages should be improved
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal

Component: translator

systemtap script
Error messages involving macros need more context. Specifically they need the
source line where the offending macro was called from.
====
# stap -I inc -g -vp4 ./macro_test.stp
Pass 1: parsed user script and 95 library script(s) using
28964virt/16096res/2472shr/13984data kb, in 200usr/30sys/248real ms.
semantic error: unable to find member 'd_flags' for struct dentry_stat_t
(alternatives: nr_dentry nr_unused age_limit want_pages dummy): operator '->'
at inc/macro_test.stpm:3:11
source: ( @dentry->d_flags )
^
Pass 2: analyzed script: 1 probe(s), 2 function(s), 1 embed(s), 0 global(s)
using 276368virt/167220res/99684shr/67864data kb, in 1560usr/80sys/1668real ms.
Pass 2: analysis failed. [man error::pass2]
====
In this case, the macro isn't the problem. The systemtap script is calling it
with the wrong type. The error message should include the offending script
line.
To duplicate this error, put the macro file in a subdirectory called 'inc'.
