Fri, 26 Jan 2018 19:58:10 -0800 (PST) Subject: [PATCH v7 09/17] RISC-V: Hard Float Support Date: Fri, 26 Jan 2018 19:57:36 -0800 Message-Id: <20180127035744.10058-10-palmer@dabbelt.com> In-Reply-To: <20180127035744.10058-1-palmer@dabbelt.com> References: <20180127035744.10058-1-palmer@dabbelt.com> Cc: Palmer Dabbelt From: Palmer Dabbelt To: libc-alpha@sourceware.org, joseph@codesourcery.com 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. 2018-01-26 Palmer Dabbelt * sysdeps/riscv/rv64/rvd/s_ceil.c: New file. *

<20180127035744.10058-1-palmer@dabbelt.com> References: <20180127035744.10058-1-palmer@dabbelt.com> Cc: Palmer Dabbelt From: Palmer Dabbelt To: libc-alpha@sourceware.org, joseph@codesourcery.com 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. 2018-01-26 Palmer Dabbelt * 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. --- sysdeps/riscv/Implies | 5 + sysdeps/riscv/Makefile | 7 + sysdeps/riscv/configure | 4 + sysdeps/riscv/configure.ac | 4 + sysdeps/riscv/nptl/Makefile | 26 +++ sysdeps/riscv/preconfigure | 71 +++++++++ sysdeps/riscv/rv64/Implies-after | 1 + sysdeps/riscv/rv64/rvd/Implies | 3 + sysdeps/riscv/rv64/rvf/Implies | 1 + sysdeps/unix/sysv/linux/riscv/Implies | 1 + sysdeps/unix/sysv/linux/riscv/Makefile | 25 +++ sysdeps/unix/sysv/linux/riscv/Versions | 11 ++ sysdeps/unix/sysv/linux/riscv/configure | 219 ++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/riscv/configure.ac | 38 +++++ sysdeps/unix/sysv/linux/riscv/ldd-rewrite.sed | 1 + sysdeps/unix/sysv/linux/riscv/rv64/Implies | 3 + sysdeps/unix/sysv/linux/riscv/rv64/Makefile | 4 + sysdeps/unix/sysv/linux/riscv/shlib-versions | 9 ++ 18 files changed, 433 insertions(+) create mode 100644 sysdeps/riscv/Implies create mode 100644 sysdeps/riscv/Makefile create mode 100644 sysdeps/riscv/configure create mode 100644 sysdeps/riscv/configure.ac create mode 100644 sysdeps/riscv/nptl/Makefile create mode 100644 sysdeps/riscv/preconfigure create mode 100644 sysdeps/riscv/rv64/Implies-after create mode 100644 sysdeps/riscv/rv64/rvd/Implies create mode 100644 sysdeps/riscv/rv64/rvf/Implies create mode 100644 sysdeps/unix/sysv/linux/riscv/Implies create mode 100644 sysdeps/unix/sysv/linux/riscv/Makefile create mode 100644 sysdeps/unix/sysv/linux/riscv/Versions create mode 100755 sysdeps/unix/sysv/linux/riscv/configure create mode 100644 sysdeps/unix/sysv/linux/riscv/configure.ac create mode 100644 sysdeps/unix/sysv/linux/riscv/ldd-rewrite.sed create mode 100644 sysdeps/unix/sysv/linux/riscv/rv64/Implies create mode 100644 sysdeps/unix/sysv/linux/riscv/rv64/Makefile create mode 100644 sysdeps/unix/sysv/linux/riscv/shlib-versions diff --git a/sysdeps/riscv/Implies b/sysdeps/riscv/Implies new file mode 100644 index 000000000000..c88325b8be16 --- /dev/null +++ b/sysdeps/riscv/Implies @@ -0,0 +1,5 @@ +init_array + +ieee754/ldbl-128 +ieee754/dbl-64 +ieee754/flt-32 diff --git a/sysdeps/riscv/Makefile b/sysdeps/riscv/Makefile new file mode 100644 index 000000000000..20a996810611 --- /dev/null +++ b/sysdeps/riscv/Makefile @@ -0,0 +1,7 @@ +ifeq ($(subdir),misc) +sysdep_headers += sys/asm.h +endif + +# RISC-V's assembler also needs to know about PIC as it changes the definition +# of some assembler macros. +ASFLAGS-.os += $(pic-ccflag) diff --git a/sysdeps/riscv/configure b/sysdeps/riscv/configure new file mode 100644 index 000000000000..53f5f1b5f113 --- /dev/null +++ b/sysdeps/riscv/configure @@ -0,0 +1,4 @@ +# This file is generated from configure.ac by Autoconf.
