libserial-newlnx: ASYNC_LOW_LATENCY patch reverted
Reports from Das Signal indicate that loadtools performance on Debian
is about the same as on Slackware, and that including or omitting the
ASYNC_LOW_LATENCY patch from Serg makes no difference. Because the
patch in question does not appear to be necessary, it is being reverted
until and unless someone other than Serg reports an actual real-world
system on which loadtools operation times are slowed compared to the
Mother's Slackware reference and on which Slackware-like performance
can be restored by setting the ASYNC_LOW_LATENCY flag.

#!/bin/sh # # This script builds and installs binutils, gcc and newlib in the order # necessary for the whole thing to work.

The present version has been concocted by # Spacefalcon the Outlaw for use in the FreeCalypso project. # # This script needs to be invoked with two arguments: # # $1: the path to the directory containing the upstream binutils, gcc # and newlib source tarballs; # # $2: the path to the directory where the built toolchain should be # installed. # # Note that there isn't a single install step at the end, instead this # script will build and install one component, then proceed to build the # next component which depends on the previous one, etc. For this reason # you should create a dedicated install directory that is writable by your # regular (non-root) uid, then run this script to populate that directory # with the toolchain. if [ $# != 2 ] then echo "usage: $0 path-to-tarballs path-to-install" exit 1 fi set -ex BASEDIR=`pwd` target_args="--target=arm-elf" # binutils come first tar xjf $1/binutils-2.21.1a.tar.bz2 # apply patches patch binutils-2.21.1/bfd/elf32-arm.c < binutils-patches/elf32-arm.patch mkdir -p binutils-build cd binutils-build ../binutils-2.21.1/configure --prefix=$2 ${target_args} --disable-nls make all make install cd .. # unpack gcc and newlib sources at the same time: the gcc build # will be pointed to newlib headers gcc_version=4.5.4 newlib_version=2.0.0 tar xjf $1/gcc-core-${gcc_version}.tar.bz2 tar xzf $1/newlib-${newlib_version}.tar.gz # patch gcc as needed cp t-arm-elf gcc-${gcc_version}/gcc/config/arm # gcc depends on binutils - add our install destination dir to the PATH # we prepend it to avoid surprises if some other arm-elf- toolchain # happens to be present already PATH=$2/bin:$PATH export PATH mkdir -p gcc-build cd gcc-build ../gcc-${gcc_version}/configure --prefix=$2 ${target_args} \ --enable-interwork --enable-multilib \ --with-cpu=arm7tdmi --with-float=soft \ --enable-languages=c --with-newlib \ --with-headers=$BASEDIR/newlib-${newlib_version}/newlib/libc/include \ --with-system-zlib --disable-shared \ --disable-nls make all-gcc make install-gcc cd .. # now we can build newlib mkdir newlib-build cd newlib-build ../newlib-${newlib_version}/configure --prefix=$2 ${target_args} \ --enable-interwork --enable-multilib \ --enable-target-optspace --enable-newlib-reent-small \ --disable-newlib-supplied-syscalls \ --disable-nls make all make install cd .. # and finally, libgcc cd gcc-build make all make install cd ..
