2018-01-29RISC-V: Build InfastructurePalmer Dabbelt19-0/+451
This patch lays out the top-level orginazition of the RISC-V port. It contains all the Implies files as well as various other fragments of build infastructure for the RISC-V port. This contains the only change to a shared file: config.h.in. RISC-V is a family of base ISAs with optional extensions. The base ISAs are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but this port currently only supports RV64I based systems. Support for RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc port supports most of the currently-defined extensions: the A extension for atomics, the M extension for multiplication, the C extension for compressed instructions, and the F/D extensions for single/double precision IEEE floating-point. Most of these extensions are handled by GCC, but glibc defines various floating-point wrappers and emulation routines as well as some atomic wrappers. We support running glibc-based programs on Linux, the support for which lives in sysdeps/unix/sysv/linux/riscv. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/Implies: New file. * sysdeps/riscv/Makefile: Likewise. * sysdeps/riscv/configure: Likewise. * sysdeps/riscv/configure.ac: Likewise. * sysdeps/riscv/nptl/Makefile: Likewise. * sysdeps/riscv/preconfigure: Likewise. * sysdeps/riscv/rv64/Implies-after: Likewise. * sysdeps/riscv/rv64/rvd/Implies: Likewise. * sysdeps/riscv/rv64/rvf/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/Versions: Likewise. * sysdeps/unix/sysv/linux/riscv/configure: Likewise. * sysdeps/unix/sysv/linux/riscv/configure.ac: Likewise. * sysdeps/unix/sysv/linux/riscv/ldd-rewrite.sed: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/shlib-versions: Likewise.

2018-01-29RISC-V: Hard Float SupportPalmer Dabbelt59-0/+2219
This patch contains hardware floating-point support for the RISC-V ISA. While we currently only support hard-float systems with both the F and D extensions, I've left the F-specific code split out into seperate folders in order to ease adding support for F-only and RV32I-based systems in the future. I gave this a quick once-over and believe I've removed all the code that implements RV32IF, RV32IFD, and RV64IF targets. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/rv64/rvd/s_ceil.c: New file. * sysdeps/riscv/rv64/rvd/s_floor.c: Likewise. * sysdeps/riscv/rv64/rvd/s_llrint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_llround.c: Likewise. * sysdeps/riscv/rv64/rvd/s_lrint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_lround.c: Likewise. * sysdeps/riscv/rv64/rvd/s_nearbyint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_round.c: Likewise. * sysdeps/riscv/rv64/rvd/s_roundeven.c: Likewise. * sysdeps/riscv/rv64/rvd/s_trunc.c: Likewise. * sysdeps/riscv/rv64/rvf/s_llrintf.c: Likewise. * sysdeps/riscv/rv64/rvf/s_llroundf.c: Likewise. * sysdeps/riscv/rv64/rvf/s_lrintf.c: Likewise. * sysdeps/riscv/rv64/rvf/s_lroundf.c: Likewise. * sysdeps/riscv/rvd/e_sqrt.c: Likewise. * sysdeps/riscv/rvd/s_copysign.c: Likewise. * sysdeps/riscv/rvd/s_finite.c: Likewise. * sysdeps/riscv/rvd/s_fma.c: Likewise. * sysdeps/riscv/rvd/s_fmax.c: Likewise. * sysdeps/riscv/rvd/s_fmin.c: Likewise. * sysdeps/riscv/rvd/s_fpclassify.c: Likewise. * sysdeps/riscv/rvd/s_isinf.c: Likewise. * sysdeps/riscv/rvd/s_isnan.c: Likewise. * sysdeps/riscv/rvd/s_issignaling.c: Likewise. * sysdeps/riscv/rvf/e_sqrtf.c: Likewise. * sysdeps/riscv/rvf/fclrexcpt.c: Likewise. * sysdeps/riscv/rvf/fegetenv.c: Likewise. * sysdeps/riscv/rvf/fegetmode.c: Likewise. * sysdeps/riscv/rvf/fegetround.c: Likewise. * sysdeps/riscv/rvf/feholdexcpt.c: Likewise. * sysdeps/riscv/rvf/fesetenv.c: Likewise. * sysdeps/riscv/rvf/fesetexcept.c: Likewise. * sysdeps/riscv/rvf/fesetmode.c: Likewise. * sysdeps/riscv/rvf/fesetround.c: Likewise. * sysdeps/riscv/rvf/feupdateenv.c: Likewise. * sysdeps/riscv/rvf/fgetexcptflg.c: Likewise. * sysdeps/riscv/rvf/fraiseexcpt.c: Likewise. * sysdeps/riscv/rvf/fsetexcptflg.c: Likewise. * sysdeps/riscv/rvf/ftestexcept.c: Likewise. * sysdeps/riscv/rvf/get-rounding-mode.h: Likewise. * sysdeps/riscv/rvf/math_private.h: Likewise. * sysdeps/riscv/rvf/s_ceilf.c: Likewise. * sysdeps/riscv/rvf/s_copysignf.c: Likewise. * sysdeps/riscv/rvf/s_finitef.c: Likewise. * sysdeps/riscv/rvf/s_floorf.c: Likewise. * sysdeps/riscv/rvf/s_fmaf.c: Likewise. * sysdeps/riscv/rvf/s_fmaxf.c: Likewise. * sysdeps/riscv/rvf/s_fminf.c: Likewise. * sysdeps/riscv/rvf/s_fpclassifyf.c: Likewise. * sysdeps/riscv/rvf/s_isinff.c: Likewise. * sysdeps/riscv/rvf/s_isnanf.c: Likewise. * sysdeps/riscv/rvf/s_issignalingf.c: Likewise. * sysdeps/riscv/rvf/s_nearbyintf.c: Likewise. * sysdeps/riscv/rvf/s_rintf.c: Likewise. * sysdeps/riscv/rvf/s_roundevenf.c: Likewise. * sysdeps/riscv/rvf/s_roundf.c: Likewise. * sysdeps/riscv/rvf/s_truncf.c: Likewise.

2018-01-29RISC-V: Thread-Local Storage SupportPalmer Dabbelt6-0/+269
This patch implements TLS support for RISC-V. We support all four standard TLS addressing modes (LE, IE, LD, and GD) when running on Linux via NPTL. There is a draft psABI document that defines our TLS ABI here https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md#thread-local-storage 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/dl-tls.h: New file. * sysdeps/riscv/libc-tls.c: Likewise. * sysdeps/riscv/nptl/tcb-offsets.sym: Likewise. * sysdeps/riscv/nptl/tls.h: Likewise. * sysdeps/riscv/stackinfo.h: Likewise.

This patch contains code that needs to directly know about the RISC-V ABI, which is specified in a work-in-progress psABI document: https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md This is meant to contain all the RISC-V code that needs to explicitly name registers or manage in-memory structure layout.

2018-01-29Add documentation for __riscv_flush_icachePalmer Dabbelt2-0/+21
This function is used by GCC to enforce ordering between data writes and instruction fetches, and while we'd prefer that users rely on the GCC intrinsic when possible this is user visible in case that's not possible. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * manual/platform.texi: Add RISC-V documenation for __riscv_flush_icache.

2018-01-29Skeleton documentation for the RISC-V portPalmer Dabbelt4-5/+15
During the upstreaming process it was suggested that I add a handful of small documentation entries about the RISC-V port, which I've collected here. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * manual/math.texi: RISC-V supports _Float128 and _Float64x.
2018-01-29sysdeps/init_array: Add PREINIT_FUNCTION to crti.SPalmer Dabbelt2-0/+19
The RISC-V port contains a crti.S that simply contains a link to PREINIT_FUNCTION (when defined). As this should be entirely generic, Joseph Myers suggested that we update the generic init_array version to contain this. Since RISC-V is the only user of init_array this won't break any existing ports. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/init_array/crti.S (.section .init_array): Add PREINIT_FUNCTION when defined.

2018-01-29Make build-many-glibcs.py clean git source directories.Joseph Myers2-0/+6
With the git checkouts of Hurd components in build-many-glibcs.py involving running autoreconf, there's a risk that generated files could be left behind by an old autoreconf run (if an old version of the sources generates those files in the source directory but a new version does not). This patch avoids that by using git clean -dxfq when updating git checkouts. In this patch, that's conditional on --replace-sources, to avoid removing any local not-checked-in files someone may have in their checkout unless the option has been specifically passed that says it's OK to blow old checkouts away, complete with any local changes to them. * scripts/build-many-glibcs.py (Context.git_checkout): Use git clean -dxfq for git updates when replacing sources.
2018-01-29Clean up build-many-glibcs.py libcilkrts disabling.Joseph Myers2-3/+9
The disabling of libcilkrts in build-many-glibcs.py has some peculiarities. It's only for the final GCC build, not the initial bootstrap one, whereas normally anything disabled for the final build should be disabled for the bootstrap one as well. And it's only for Hurd, when it's more natural by analogy with the libsanitizer disabling to disable this library unconditionally, not only for targets where it's known to break. This patch cleans up that disabling accordingly, adding a comment so it's obvious it can be removed once GCC 7 is too old to build glibc. * scripts/build-many-glibcs.py (Config.build_gcc): Use --disable-libcilkrts unconditionally, not just for the final GCC build for Hurd.
2018-01-29Use Linux 4.15 in build-many-glibcs.py.Joseph Myers2-1/+6
This patch makes build-many-glibcs.py use Linux 4.15. Other glibc updates for Linux 4.15 can wait until after the 2.27 release. * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 4.15.
