Changes to the built-in specification occurred after early patches
added support for these. The name of vec_clzm became vec_cntlzm,
and vec_ctzm became vec_cnttzm. Four of the overloaded forms of
vec_gnb were removed, and the fourth argument redefined as an
unsigned int,

This libbacktrace patch fixes the ELF support so that after reading
symbol information we don't free the strtab, even if we encounter an
error later while reading debug info. This fixes programs that try to
get symbol information even if they can't get backtrace information.

This patch to libbacktrace adds Mach-O support. Bootstrapped and
tested on macOS. Most tests pass, but a couple still fail. This is

This patch to libbacktrace handles short reads correctly. Short reads
are unlikely, but they can reportedly happen when the debug sections
are very large and we aren't using mmap. Bootstrapped and ran
libbacktrace tests on x86_64-pc-linux-gnu. Committed to mainline.

This patch to libbacktrace changes it to read the debug sections as
individual sections if they are very large or are far apart. This
uses less memory in some cases, and fixes some cases on 32-bit
systems. In particular this fixes one of the problems in

Hi,
the attached should be mostly self-explaining. Division by zero handling
appeared to be incomplete. It was not dealt with properly when occurring
in declaration statements. We now try to handle this.
OK for mainline?

two-types-6.c never emitted the warning, even in 4.5/4.6, and pr93382.c
