2022-04-12Merge pull request #1054 from riscv-collab/with-isa-spec2022.04.12Kito Cheng1-0/+8
Add --with-isa-spec option to configure
2022-04-11Add --with-isa-spec option to configureKito Cheng1-0/+8
Set the default version to 2.2 for now, and once we bump to GCC 12 we will bump that to 20191213.
2022-02-24Prevent musl riscv32 buildsFlorian Hofhammer1-1/+5
The upstream musl libc does not support 32bit RISC-V builds. We therefore only allow building the 64bit version (i.e., riscv64-unknown-linux-musl-). Signed-off-by: Florian Hofhammer <florian.hofhammer@fhofhammer.de>
2022-02-24Add musl libc submoduleFlorian Hofhammer1-1/+1
Since musl is already incorporated into the build system (see for example configure.ac, Makefile.in), this patch adds a submodule for musl based on the current v1.2.2 release. The GitHub Actions configurations have also been updated to include the musl based toolchain. Signed-off-by: Florian Hofhammer <florian.hofhammer@fhofhammer.de>
2022-02-24Update glibc and newlib pathsFlorian Hofhammer1-2/+2
Both the glibc and newlib submodules are already pointing to the upstream repositories where development happens. Since they are therefore not referring to RISC-V specific forks, this patch unifies the directory naming by only prepending the "riscv-" prefix to submodules that point to repositories in the riscv-collab Github organization. Signed-off-by: Florian Hofhammer <florian.hofhammer@fhofhammer.de>
2022-02-24Use "qemu", not "riscv-qemu", as the default QEMU sourcePalmer Dabbelt1-8/+8
The recent addition of an override for the QEMU source directory left the default pointing to the wrong submodule. Fixes: b83ee52 ("Allow source-override for QEMU") Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2022-02-10Allow source-override for QEMUChristoph Muellner1-0/+1
This patch introduces a configure-time source-dir override for QEMU similar to the existing overrides for the other toolchain sources. Signed-off-by: Christoph Muellner <cmuellner@linux.com>
2020-11-06Add --with-multilib-generator optionKito Cheng1-1/+13
2020-02-07Correct previous configure fix. Edit configure.ac and regenerate.Jim Wilson1-1/+1
2019-11-05Don't enable gcc checking by default.Jim Wilson1-5/+5
Also, support all gcc checking options instead of just yes and release. Also, fix copy-and-paste error in cmodel support refering to gcc checking.
2019-11-01Add configure options to set target C and C++ compiler flags.Jim Wilson1-0/+15
This is a partial fix for pull request #530, allowing people to use -mno-fdiv for library compiles.
2019-09-29Fix default LINUX_HEADERS_SRCDIR pathAlbert Ou1-1/+1
The --with-headers argument must point to the `include' subdirectory.

Add option to specify source tree of each component
2019-09-27Add option to specify source tree of each componentKito Cheng1-0/+32
2019-09-26Fix awk/sed wrapper pathsAlbert Ou1-2/+2
These wrappers are still necessary on non-GNU platforms; glibc makefile rules invoke `sed' directly with GNU extensions.
2019-02-15Add toplevel --with-tune= configure option.Jim Wilson1-0/+8
2018-10-10Remove --disable-atomic option, which stopped working about 2 years ago.Jim Wilson1-7/+0

2017-09-13Split the glibc and newlib multilib names in the MakefilePalmer Dabbelt1-2/+6
2017-09-06Add a "--disable-gdb" argumentPalmer Dabbelt1-0/+11
2017-08-20Always set the multilib listPalmer Dabbelt1-1/+1
2017-05-31Add support for --with-guile configure flagJohannes Löthberg1-0/+11
And re-run autoreconf to generate the configure script. Signed-off-by: Johannes Löthberg <johannes@kyriasis.com>
2017-05-03Allow the user to flip "--with-system-zlib"Palmer Dabbelt1-0/+11
We need this to have different polarity for different platforms (Windows vs RedHat). I don't know how to autodetect this for now, so I'm just doing it manually.
2017-05-03Add a "--with-host" argumentPalmer Dabbelt1-0/+11
I need to set this in order to build the Windows tools.
2017-05-01Add the "--with-cmodel" configure argumentPalmer Dabbelt1-0/+10
This lets users select the code model when building the tools.
2017-02-01bump; change linux default to RVCAndrew Waterman1-6/+6
2016-12-22Default arch is rv64g, not ERRORAndrew Waterman1-2/+3
2016-12-14Auto detect default value for --with-abi if not givenKito Cheng1-2/+15
2016-12-12Multilibs go in /lib${XLEN}/${ABI}/, e.g. /lib64/lp64/Andrew Waterman1-52/+12
2016-12-12Incorporate new GCC flags and multilib supportAndrew Waterman1-1/+5
2016-11-04Add --enable-gcc-checking to configure option (#191)Kito Cheng1-0/+10
2016-10-13Support an RV32F compilerAndrew Waterman1-8/+3
Soft-float calling convention is default, but an alternate hard-float calling convention (with doubles passed as in soft-float, but floats passed as in hard-float) is supported.
2016-08-10Add retry flag to curl for bad networksColin Schmidt1-1/+1
The buildbot seems to be hammering the newlib servers causing dropped connections so we'll try to backoff and retry.
2016-06-01Add -L option for curl to follow redirects.Masanori Ogino1-1/+1
It is necessary to fetch tarballs from e.g. GitHub. Signed-off-by: Masanori Ogino <masanori.ogino@gmail.com>
2016-05-30Improve handling of --with-arch in configure.acGarret Kelly1-11/+34
Augment the handling of --with-arch such that it can properly set XLEN, atomics flags, and floating point flags. The original --enable-atomics/float flags are still respected, but if --with-arch is provided then it supersedes other options.
2016-04-05Start passing "--enable-soft-float"-like argumentsPalmer Dabbelt1-2/+8
It's no longer the case that building the toolchain with "--disable-float" turns off floating-point by default. This passes the correct arguments to all the various sub-configures in order to ask for floating-point support to be either enabled or disabled.
2015-09-10Fix --enable-multilib for Newlib toolchainAndrew Waterman1-1/+1
You now need to explicitly pass this flag to turn on multilib support.
2015-07-23Don't pass "--with-arch" by defaultPalmer Dabbelt1-2/+2
I commited this too quickly last time and it's been breaking a whole bunch of stuff. Until I managed to get multilib working in a sane way, I'm just going to go ahead and turn it off by default. You can still pass "--with-arch", but doing so while also passing things like "--enable-multilib" or "--disable-atomics" might have unexpected results.
2015-07-02Default to IMAFD, not G for --with-archPalmer Dabbelt1-3/+3
G doesn't actually work.
2015-07-02Rename "--with-base-isa" to "--with-arch"Palmer Dabbelt1-5/+5
This matches the GCC configure option.
2015-07-01Add "--with-base-isa" support to autoconfPalmer Dabbelt1-0/+7
This allows someone to build a RV32I toolchain without going in and messing with the Makefile directly.
2015-04-11Avoid wrapping GNU sed/awk on systems where that's the defaultPalmer Dabbelt1-2/+2
I have no idea why, but the installed "sed" wrapper never terminates on RHEL. If I don't use the wrappen the the tools build fine, so this just uses the already set autoconf variables to attempt to determine if the system sed/awk are gsed/gawk and if they are then this avoids using the wrappers. There's a few oddities here: * I have no idea why the sed wrapper fails, as it seems super safe. * I haven't run into any awk problems, but I figured I'd treat it the same as it isn't any harder. * We shouldn't have to support 10 year old distributions. Hopefully this doesn't break anyone's builds...
2015-04-11Actually fix the build on RHELPalmer Dabbelt1-4/+4
Looks like I managed to screw up my last commit -- I dropped an apparently significant trailing ,.
2015-04-08Download GCC's library dependencies if they don't existPalmer Dabbelt1-8/+10
Some systems don't have things like GMP, MPFR, and friends installed. Rather than requiring them to be installed as root, this uses a bit of GCC's built-in functionality to download these libraries and build them along with GCC. This allows the tools to build on Red Hat, but only if you install newer host tools (I have GCC, make, and texinfo).
2015-03-06configure/Makefile: Add support for more options.Darius Rad1-0/+35
Add support to configure and Makefile.in for --disable-atomic, --disable-float, and --enable-multilib.
2015-03-03Add "--with-xlen" to autoconfPalmer Dabbelt1-0/+7
This allows users to set the register bitwidth via an autoconf option rather than an environment variable.
2015-03-03configure: Fix --enable-linux option.Darius Rad1-3/+8
Use AS_HELP_STRING to properly format help text. Properly handle both states of the option and the default.
2015-02-20Support multiple file transfer utilitiesAlbert Ou1-0/+9
Select between curl(1), wget(1), and ftp(1) through autoconf. Wherever possible, automatically follow HTTP location redirects and enable passive FTP mode. Explicitly instruct tar(1) to read from stdin since this is far from universal behavior if unspecified: The default file is /dev/sa0 in FreeBSD, /dev/rst0 in NetBSD and OpenBSD, etc.
2015-02-20Centralize GNU utility checks in autoconfAlbert Ou1-13/+27
Tests for program presence, such as those formerly embedded in the top-level Makefile for gawk and gsed, are better suited for autoconf. Note that it is not sufficient to merely export AWK and SED environment variables, as packages may still directly invoke awk(1) and sed(1) with non-standard features independent of the autotools framework. Wrapper scripts therefore remain necessary, although these are now generated by the configure script to avoid hard-coded paths. Do not assume the existence of /bin/bash on all systems.
