RISC-V:[gprofng] Minimal support gprofng for riscv.
ChangeLog: Add target riscv to --enable-gprofng. 2024-07-04 Yixuan Chen <chenyixuan@iscas.ac.cn> * configure: Add riscv. * configure.ac: Add riscv. gprofng/ChangeLog: Minimal support gprofng for riscv. 2024-07-04 Yixuan Chen <chenyixuan@iscas.ac.cn> * gprofng/common/core_pcbe.c (core_pcbe_init): Add RISC-V vendor conditon. (defined): Add riscv. * gprofng/common/cpuid.c (defined): Add risc-v hwprobe. * gprofng/common/gp-defs.h (TOK_A_RISCV): Add riscv. (defined): Add riscv. (ARCH_RISCV): Add riscv. * gprofng/common/hwc_cpus.h: Add RISC-V vendor. * gprofng/common/hwcfuncs.h (HW_INTERVAL_TYPE): Remove useless defination. * gprofng/configure: Add riscv. * gprofng/configure.ac: Add riscv. * gprofng/libcollector/hwprofile.h (ARCH): Add RISC-V register. (CONTEXT_PC): Add RISC-V register. (CONTEXT_FP): Add RISC-V register. (CONTEXT_SP): Add RISC-V register. (SETFUNCTIONCONTEXT): * gprofng/libcollector/libcol_util.c (__collector_util_init): Fix libc open condition. * gprofng/libcollector/libcol_util.h (ARCH): Add RISC-V. * gprofng/libcollector/unwind.c (ARCH): Add RISC-V register. (GET_PC): Add RISC-V register. (GET_SP): Add RISC-V register. (GET_FP): Add RISC-V register. (FILL_CONTEXT): * gprofng/src/DbeSession.cc (ARCH): Add RISC-V. * gprofng/src/Disasm.cc (Disasm::disasm_open): Add RISC-V. * gprofng/src/Experiment.cc (Experiment::ExperimentHandler::startElement): Add RISC-V. * gprofng/src/checks.cc (ARCH): Add RISC-V. * gprofng/src/collctrl.cc (defined): Set risc-v cpu frequency to 1000MHz as default for now, will fix when I find a better method to get cpu frequency. (read_cpuinfo): Add "mvendorid" condition according to risc-v /proc/cpuinfo file content. * gprofng/src/dbe_types.h (enum Platform_t): Add RISC-V.
