Request for RISCV LLVM compiler option in SDK

[matsobdev]

because... why not :D But messing with scripts and hardcoding, and deleting stuff, managed to compile some program that works. There was some warnings and SDK required some changes. Stable release and top-of-tree both has RISCV LLVM option. Latter one has newer 19.0.0 (and it's GCC/LLVM combo), and it works with -march=rv32ima_zicsr_zifencei_zba_zbb_zbs_zbkb_zca_zcb_zcmp, that is required after changing instruction:

pico-sdk/src/rp2_common/hardware_irq/irq_handler_chain.S

Line 75 in 95ea6ac

.insn 0xb842 // cm.push {ra}, -16: Save ultimate return address

and

pico-sdk/src/rp2_common/hardware_irq/irq_handler_chain.S

Line 91 in 95ea6ac

.insn 0xbe42 // cm.popret {ra}, 16

to its commented out form. Stable (16 something) was not complying with rv32imac_zicsr_zifencei_zba_zbb_zbs_zbkb. They both are shipped with newlib so set(PICO_CLIB newlib). Pico 2 W has similar instruction incompatibility somewhere in cyw43driver I believe, but there was not comment for that :D So deleting it, and it compiled spiting out uf2 file. I don't have Pico 2 W to test it, but I bet it might lack one instruction. I didn't dig deep enough for the replacement. Anyway, compiler is available (for Linux and macOS only in a binary form) and at the first glance it works.

For Pico 2 W, the problematic line is:

pico-sdk/src/rp2_common/pico_cyw43_driver/cyw43_bus_pio_spi.c

Line 90 in 95ea6ac

: "+l" (a), "=l" (tmp));

but I think solution is there #1922:

 : "+r" (a), "=r" (tmp)); 

[kilograham]

I had a little play, and the linker crashes with stdio_usb e.g. hello_usb from pico-examples.

I dont have a lot of cycles to look at this right now, but if you want to have a poke around, that might help me drop this in in the next release as a "pre-release" - it would be good if it could compile everything though ;-)

[kilograham]

actually i did just check; it is anything that uses tinyusb

Doesn't tell you much; i didn't find the right version of the code - my guess is a linker bug

And the last one is the same for pico-examples. But set(PICO_DEFAULT_BINARY_TYPE=copy_to_ram) and set(PICO_COPY_TO_RAM=1) seems to do nothting - won't set binary type (they do nothing, it should be set(PICO_DEFAULT_BINARY_TYPE copy_to_ram)). Local pico_set_binary_type(<program> <binary_type>) is successfull at doing that.

[matsobdev]

Closed by accident.

BTW, succesfull and failing one have both

Is it safe?

And yes, with default binary type and:

pico_enable_stdio_usb(<program> 0)
pico_enable_stdio_uart(<program> 1)

it compiles just fine:

it compiles. Same warnings repeats:

^

But for no_flash pico-examples new error appears:

/media/mateush/Dane/Download/Pico_2/riscv-embecosm-embedded-ubuntu2004-20250309/bin/riscv32-unknown-elf-ld: blink_simple/CMakeFiles/blink_simple.dir/home/mateush/pico-sdk-2.1.1/src/rp2_common/pico_standard_binary_info/standard_binary_info.c.o:(.rodata.__bi_26+0x8): undefined reference to `__flash_binary_end'
riscv32-unknown-elf-clang++: error: ld command failed with exit code 1 (use -v to see invocation)

For pico2_w it will fail due to RAM overflow at some examples when copy_to_ram. Some standalone project comiles with no_flash.

PS. My bad, it should be set(PICO_DEFAULT_BINARY_TYPE copy_to_ram) not set(PICO_DEFAULT_BINARY_TYPE=copy_to_ram).
