    To get a bit more specific: Version 2. In this case we can emit a single fmul. The code sizes for objects produced by GCC for each of these architectures is shown below:. Issues for consideration Should the -mabi string be parsed case insensitively? Top of page. Find centralized, trusted content and collaborate around the technologies you use most. They allocate stack space for the registers and then save ra and the appropriate number of registers from s0 - s

    These command-line options are defined for RISC-V targets: is the default when GCC is configured for a ' riscv64be-*-* ' or ' riscv32be-*-* ' target.Active Oldest Votes.Forum Gcc risc v target

    the target ABIs. Machine Architecture and ABI. When compiling for RISC-V figuring out the compiler target correct is one of the first.The default is -mplt.

    Whether ordering should be enforced on the ISA string (e.g. currently rv32imafd is accepted by GCC but rv32iamfd is not). Specifying the target ABI with -mabi.This is a common problem when dealing with legacy libraries that need to be integrated into newer systems so we've designed our compiler arguments and multilib paths to cleanly integrate with this workflow.

    -mtune=CODENAME selects the microarchitecture to target. This informs GCC about the performance of each instruction, allowing it to perform.Otherwise, Clang would not find these tools due to their prefixes not quite matching the target name.

    The default is set depending on whether the processor we are optimizing for supports fast unaligned access or not.

    There's no way the compiler could generate code for an ISA that requires passing arguments in F registers if it doesn't have access to the instructions required to access those registers.Forum Gcc risc v target

    The -Os flag was used to instruct the compiler to optimise for code size.

    The alternative is to use assembler macros instead, which may limit optimization.
