ftmemsim-valgrind/coregrind/pub_core_options.h
Bart Van Assche 908268e4a0 Add command-line option --fair-sched=[no|yes|try]. Use --fair-sched=try 
when running the annotate_hbefore regression test. Closes #270006.

To do: update manual.

/* An array of strings harvested from --require-text-symbol=
flags.
Each string specifies a pair: a soname pattern and a text symbol
name pattern, separated by a colon. The patterns can be written
using the normal "?" and "*" wildcards. For example:
":*libc.so*:foo?bar".
These flags take effect when reading debuginfo from objects. If an
object is loaded and the object's soname matches the soname
component of one of the specified pairs, then Valgrind will examine
all the text symbol names in the object. If none of them match the
symbol name component of that same specification, then the run is
aborted, with an error message.
The purpose of this is to support reliable usage of marked-up
libraries. For example, suppose we have a version of GCC's
libgomp.so which has been marked up with annotations to support
Helgrind. It is only too easy and confusing to load the 'wrong'
libgomp.so into the application. So the idea is: add a text symbol
in the marked-up library (eg), "annotated_for_helgrind_3_6", and
then give the flag
--require-text-symbol=:*libgomp*so*:annotated_for_helgrind_3_6
so that when libgomp.so is loaded, we scan the symbol table, and if
the symbol isn't present the run is aborted, rather than continuing
silently with the un-marked-up library. Note that you should put
the entire flag in quotes to stop shells messing up the * and ?
wildcards. */
