2018-02-21aarch64: Fix bits/utmp.h for GCC 8HEADglibc-2.27-amp-branchSzabolcs Nagy
The same suppression of -Wstringop-truncation warnings as in commit 7532837d7b03b3ca5b9a63d77a5bd81dd23f3d9c but for aarch64. 2018-02-21 Szabolcs Nagy <szabolcs.nagy@arm.com> * sysdeps/unix/sysv/linux/aarch64/bits/utmp.h (struct utmp): Use __attribute_nonstring__.
2018-02-02aarch64: Update ILP32 abilistsSzabolcs Nagy
Update libc and libm abilists with copy_file_range, mlock2, pkey_* and _FloatN related symbols. Remove pthread_self from the libpthread abilist. This will need to be merged with the initial ilp32 abilist commit. 2018-01-26 Szabolcs Nagy <szabolcs.nagy@arm.com> * sysdeps/unix/sysv/linux/aarch64/ilp32/libc.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/ilp32/libm.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/ilp32/libpthread.abilist: Update.
2018-02-02aarch64: Fix jmp_buf-macros.h for ILP32.Szabolcs Nagy
The offset is different on ILP32 because __saved_mask is 4 byte aligned. 2017-11-28 Szabolcs Nagy <szabolcs.nagy@arm.com> * sysdeps/unix/sysv/linux/aarch64/jmp_buf-macros.h (SAVED_MASK_OFFSET): Fix for ILP32.
2018-02-02aarch64: Update ILP32 abilistsSzabolcs Nagy
Update libc and libm abilists with memfd_create and new _FloatN symbols. Remove __nis_hash and __p_secstodate from libnsl and libresolv abilists. This will need to be merged with the initial ilp32 abilist commit. 2017-11-27 Szabolcs Nagy <szabolcs.nagy@arm.com> * sysdeps/unix/sysv/linux/aarch64/ilp32/libc.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/ilp32/libm.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/ilp32/libnsl.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/ilp32/libresolv.abilist: Update.
2018-02-02aarch64: Update ILP32 abilistsSzabolcs Nagy
Update abilist files because a number of symbols got removed for GLIBC_2.27. ILP32 now needs separate localplt.data as well because it has no matherr PLT anymore. (Eventually this will be merged into the initial abilist commit.) 2017-09-29 Szabolcs Nagy <szabolcs.nagy@arm.com> * sysdeps/unix/sysv/linux/aarch64/ilp32/libc.abilist (__nss_group_lookup): Remove. (__nss_hosts_lookup): Remove. (__nss_passwd_lookup): Remove. * sysdeps/unix/sysv/linux/aarch64/ilp32/libm.abilist (_LIB_VERSION): Remove. (matherr): Remove. (pow10): Remove. (pow10f): Remove.

2018-02-02aarch64: Fix ipc_perm definition for ILP32Steve Ellcey
Here is another aarch64 ILP32 patch. The mode field in ipc_perm in ILP32 should be a 16 bit field, not a 32 bit one. This was out-of-sync with what the kernel had. This was causing sysvipc/test-sysvsem to fail in ILP32 mode. 2017-09-01 Yury Norov <ynorov@caviumnetworks.com> Steve Ellcey <sellcey@cavium.com> * sysdeps/unix/sysv/linux/aarch64/bits/ipc.h (ipc_perm): Ifdef and pad the mode field for ILP32.
2018-02-02aarch64: Set ilp32 minimum linux version to 4.12Szabolcs Nagy

2018-01-29RISC-V: Build InfastructurePalmer Dabbelt
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 Dabbelt
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: Generic <math.h> and soft-fp RoutinesPalmer Dabbelt
This patch contains the miscellaneous math routines and headers we have implemented for RISC-V.

2018-01-29RISC-V: Thread-Local Storage SupportPalmer Dabbelt
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.
2018-01-29RISC-V: ABI ImplementationPalmer Dabbelt
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. This does not contain any of the Linux-specific code. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/__longjmp.S: New file. * sysdeps/riscv/backtrace.c: Likewise. * sysdeps/riscv/bits/endian.h: Likewise. * sysdeps/riscv/bits/setjmp.h: Likewise. * sysdeps/riscv/bits/wordsize.h: Likewise. * sysdeps/riscv/bsd-_setjmp.c: Likewise. * sysdeps/riscv/bsd-setjmp.c: Likewise. * sysdeps/riscv/dl-trampoline.S: Likewise. * sysdeps/riscv/gccframe.h: Likewise. * sysdeps/riscv/jmpbuf-offsets.h: Likewise. * sysdeps/riscv/jmpbuf-unwind.h: Likewise. * sysdeps/riscv/machine-gmon.h: Likewise. * sysdeps/riscv/memusage.h: Likewise. * sysdeps/riscv/setjmp.S: Likewise. * sysdeps/riscv/sys/asm.h: Likewise. * sysdeps/riscv/tls-macros.h: Likewise.
2018-01-29Add documentation for __riscv_flush_icachePalmer Dabbelt
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.
2018-01-29Add RISC-V entries to config.h.inPalmer Dabbelt
These were autogenerated. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * config.h.in: Regenerate.
2018-01-29Skeleton documentation for the RISC-V portPalmer Dabbelt
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.
