`riscv-gnu-toolchain` fails to compile simple test program (CMake Cross Compiler) #4

Open Quaker762 opened 2 years ago

Quaker762 commented 2 years ago

The toolchain has seemingly been configured incorrectly. Observe the following output from CMake:

[quaker@threadripper build]$ cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain/riscv_gcc.cmake ../

-- The C compiler identification is unknown
-- Check for working C compiler: /usr/bin/riscv32-unknown-elf-gcc
-- Check for working C compiler: /usr/bin/riscv32-unknown-elf-gcc - broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:69 (message):
  The C compiler

    "/usr/bin/riscv32-unknown-elf-gcc"

  is not able to compile a simple test program.

  It fails with the following output:

It seems the compiler is invoking the host's as, which is insanity.

The command riscv32-unknown-elf-gcc --target-help also fails:

[quaker@threadripper build]$ riscv32-unknown-elf-gcc --target-help
The following options are target specific:
  -mabi=                      Specify integer and floating-point calling convention.
  -malign-data=               Use the given data alignment.
  -march=                     Generate code for given RISC-V ISA (e.g. RV64IM).  ISA strings must be lower-case.
  -mbig-endian                Assume target CPU is configured as big endian.
  -mbranch-cost=N             Set the cost of branches to roughly N instructions.
  -mcmodel=                   Specify the code model.
  -mcpu=PROCESSOR             Use architecture of and optimize the output for PROCESSOR.
  -mdiv                       Use hardware instructions for integer division.
  -mexplicit-relocs           Use %reloc() operators, rather than assembly macros, to load addresses.
  -mfdiv                      Use hardware floating-point divide and square root instructions.
  -misa-spec=                 Set the version of RISC-V ISA spec.
  -mlittle-endian             Assume target CPU is configured as little endian.
  -mplt                       When generating -fpic code, allow the use of PLTs. Ignored for fno-pic.
  -mpreferred-stack-boundary= Attempt to keep stack aligned to this power of 2.
  -mrelax                     Take advantage of linker relaxations to reduce the number of instructions required to materialize symbol addresses.
  -mriscv-attribute           Emit RISC-V ELF attribute.
  -msave-restore              Use smaller but slower prologue and epilogue code.
  -mshorten-memrefs           Convert BASE + LARGE_OFFSET addresses to NEW_BASE + SMALL_OFFSET to allow more memory accesses to be generated as compressed instructions.  Currently targets 32-bit integer load/stores.
  -msmall-data-limit=N        Put global and static data smaller than <number> bytes into a special section (on some targets).
  -mstack-protector-guard-offset= Use the given offset for addressing the stack-protector guard.
  -mstack-protector-guard-reg= Use the given base register for addressing the stack-protector guard.
  -mstack-protector-guard=    Use given stack-protector guard.
  -mstrict-align              Do not generate unaligned memory accesses.
  -mtune=PROCESSOR            Optimize the output for PROCESSOR.

  Supported ABIs (for use with the -mabi= option):
    ilp32 ilp32d ilp32e ilp32f lp64 lp64d lp64f

  Known code models (for use with the -mcmodel= option):
    medany medlow

  Supported ISA specs (for use with the -misa-spec= option):
    2.2 20190608 20191213

  Known data alignment choices (for use with the -malign-data= option):
    natural xlen

  Valid arguments to -mstack-protector-guard=:
    global tls

Assembler options
=================

Use "-Wa,OPTION" to pass "OPTION" to the assembler.

You could try my pr above, it attempts to fix this problem.

Reconfigure the riscv repo to support imac_zicsr extension and you will solve this problem.
