2023-09-25Merge pull request #1293 from riscv-collab/extra-multi-lib-test2023.09.26Kito Cheng1-0/+10
Add --with-extra-multilib-test option
2023-08-08Fix bug in configure.ac and regenerate configureJeremy Bennett1-2/+1
* configure: Regenerated. * configure.ac: Remove redundant AS_HELP_STRING when testing enable_debug_info; add comment to use Autoconf 2.69. Signed-off-by: Jeremy Bennett <jeremy.bennett@embecosm.com>
2023-07-11Add --with-extra-multilib-test optionKito Cheng1-0/+10
NOTE: This is toolchain developer facing feature. This allow user to add extra testing multi-lib arch, it's useful when develop and/or testing new extensions. Usage: --with-extra-multilib-test="arch-abi[;arch-abi]" e.g. linux enable enabled multilib, so default will build with follwoing configuration: lib32/ilp32;@march=rv32imac@mabi=ilp32 lib32/ilp32d;@march=rv32imafdc@mabi=ilp32d lib64/lp64;@march=rv64imac@mabi=lp64 lib64/lp64d;@march=rv64imafdc@mabi=lp64d But you want to testing more on vector stuffs like rv32gcv and rv64gcv, then you can configure with `--with-extra-multilib-test="rv32gcv-ilp32d;rv64gcv;lp64d"` Then the testing will run rv32imac-ilp32 rv32imafdc-ilp32d rv64imac-lp64 rv64imafdc-lp64d and rv32gcv-ilp32d;rv64gcv;lp64d! NOTE: Extra multilib test settings still require existing multilib has support those extra settings, e.g. you can't add rv32imafc_zbb-ilp32f on above example since no compatible multilib has provided.

Update readme about llvm & qemu examples Co-authored-by: Kito Cheng <kito.cheng@sifive.com>
2023-05-17Add support to build LLVM/clang with C and C++ supportChristoph Müllner1-0/+12
We currently have a stale "llvm" branch, that does not build. However, there is clear demand in the RISC-V toolchain community for a working LLVM on top of a recent GNU toolchain. In order to build such a toolchain, quite some LLVM and clang know-how is required to avoid path issues at LLVM build time or later when using clang. The main purpose of this commit is to demonstrate a way to combine the RISC-V GNU toolchain repo with LLVM, with the intent to save others hours of frustration, debugging time or support time.

2022-09-29gdb: Bump GDB version to 12.1 (#1132)Christoph Müllner1-1/+1
GDB still defaults to 10.1 from the (already archived) riscv-binutils-gdb repo. Let's bump the version to 12.1 and use the upstream git repo instead. Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu> Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu>

2022-05-12Allow users to build QEMU with system-mode emulationPalmer Dabbelt1-0/+11
I'm trying to clean up some of my test scripts, and one issue is that I've got two QEMU builds: one for user-mode emulation and one for system-mode emulation. This adds an autoconf flag that allows me to avoid the duplication. Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2022-05-11Put the linux-headers bits togetherPalmer Dabbelt1-4/+4
These got split up by my libsanitizer patch. Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2022-04-21Add an "--enable-libsanitizer" configure-time argumentPalmer Dabbelt1-0/+11
This lets users select whether or not to build libsanitizer, which currently does not support rv32 and thus can't be enabled by default. Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>

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>

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.

2019-09-26Fix 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.

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.

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.

2016-05-30Improve 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.
