GCC's config/ChangeLog since the last time this merge was done (in the binutils-gdb commit0b4d000cc4) is included at the end of this commit message. It is worth noting that the binutils-gdb commit301a9420d9added the file config/debuginfod.m4 which is not present in GCC's config/ directory. This file is preserved, unmodified, after this commit. In order to regenerate all of the configure files, I configured with --enable-maintainer-mode, and built the 'all' target. I then did the same thing on a source tree without this patch, and only committed those files that changed when this patch was added.

# SYNOPSIS
|
|
#
|
|
# AX_COUNT_CPUS([ACTION-IF-DETECTED],[ACTION-IF-NOT-DETECTED])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Attempt to count the number of logical processor cores (including
|
|
# virtual and HT cores) currently available to use on the machine and
|
|
# place detected value in CPU_COUNT variable.
|
|
#
|
|
# On successful detection, ACTION-IF-DETECTED is executed if present. If
|
|
# the detection fails, then ACTION-IF-NOT-DETECTED is triggered. The
|
|
# default ACTION-IF-NOT-DETECTED is to set CPU_COUNT to 1.
