This is based on the original work from Zong Li [1] and has been updated to use a 64-bit time_t. This requires a 5.4+ kernel and all of the testing has been done using the 5.4 stable kernel. Nothing fails when running ./scripts/build-many-glibcs.py (for all targets) on my x86-64 machine. This is the current list of tests that fail when running inside QEMU RV32 system emulation on the 5.4 kernel: FAIL: elf/tst-ldconfig-ld_so_conf-update FAIL: io/tst-lockf FAIL: misc/test-errno-linux FAIL: nss/tst-nss-files-hosts-long FAIL: resolv/tst-resolv-res_init-thread FAIL: stdio-common/bug22 FAIL: stdlib/tst-strfrom FAIL: stdlib/tst-strfrom-locale FAIL: sysvipc/test-sysvmsg ---Links--- 1:

found here: https://github.com/alistair23/glibc/tree/alistair/rv32.1 ---Changelog--- v1: - Update based from feedback on RFCv6 - Improve test passing - There are only 9 tests failing now - Rebase on Lukasz's work - Send only the RV32 specific patches (other patches are already merged or on the list) RFC v6: - Rebase on top of accetpted patches - Fix issues so that the tests actually run RFC v5: - Hopefully finally get the correct layout for the *64 syscalls - Sort out the Changelog RFC v4: - Continue to fix things that weren't working - Update the coding style to match glibc - Update the __ASSUME_TIME64_SYSCALLS work to better match Lukasz's work RFC v3: - Remove all "Hack" patches - Incorporate upstream comments - Ensure we don't break RV64 - Lot's more testing and fixes RFC v2: - Add Lukasz's patches - Update the non HACK syscalls after feedback - define __ASSUME_TIME64_SYSCALLS and __ASSUME_RLIM64_SYSCALLS - Remove lockf64.c - Other smaller changes from RFC v1 Alistair Francis (9): RISC-V: Use 64-bit time_t and off_t for RV32 and RV64 RISC-V: Define __NR_* as __NR_*_time64/64 for 32-bit RISC-V: Add support for 32-bit vDSO calls RISC-V: Add socket-constants.h for RV32 RISC-V: Add arch-syscall.h for RV32 RISC-V: nptl: update default pthread-offsets.h RISC-V: Add ABI lists RISC-V: Add the RV32 libm-test-ulps riscv32: Specify the arch_minimum_kernel as 5.4 Zong Li (9): RISC-V: Support dynamic loader for the 32-bit RISC-V: Add path of library directories for the 32-bit RISC-V: The ABI implementation for 32-bit RISC-V: Hard float support for 32-bit RISC-V: Fix llrint and llround missing exceptions on RV32 RISC-V: Build Infastructure for 32-bit RISC-V: Add rv32 path to RTLDLIST in ldd Documentation for the RISC-V 32-bit port Add RISC-V 32-bit target to
