I failed to update the patch I posted after making a correct to symbol
poisoning, that had caused builds to fail right away, sorry. Thanks,
Rainer, for catching the error.
Here's the patch that actually passed regstrap on native i686 and
x86_64-linux-gnu, and fixed numerous regressions on cross builds.
Ok to install?
[LVU, IEPM] several new controlling options
Given that the minimum insn length is not generally reliable to tell
whether an insn actually advances PC, this patch disables the locview
list optimizations that can only be done when can tell it.
The preexisting logic is retained, however, and can be enabled with
the newly-introduced -ginternal-reset-location-view. This is now
enabled by default only if the target defines a hook that may override
or defer to the preexisting logic. The negated command line option
can then be used should errors still be encountered.
We also introduce options to control whether to assume .loc and view
support in the assembler, and to control whether to output inline
entry points (and views) from markers.
i see assembler slow downs with these location view patches
