minus-squareFizzyOrange@programming.devcakelinkfedilinkarrow-up0·2 months ago this is about non-generic code in generic header. (a << 16) | b is about the most generic code you can get. How is that remotely RISC-V specific?
minus-squarezygo_histo_morpheus@programming.devlinkfedilinkarrow-up0·2 months agoMaking a u32 pointer from to u16’s isn’t a generic operation because it has to make assumptions about how the pointers work (in particular what endianess they have)
minus-squareFizzyOrange@programming.devcakelinkfedilinkarrow-up0·2 months agoWhat makes you think it’s making a pointer? Nobody said anything about that.
minus-squarezygo_histo_morpheus@programming.devlinkfedilinkarrow-up0·1 month agoOh my bad I don’t know where I got that from lol
minus-squareFizzyOrange@programming.devcakelinkfedilinkarrow-up0·1 month agoNw. You’re also wrong about endianness. This function would be written exactly the same irrespective of endianness: uint32_t u16_high_low_to_u32(uint16_t high, uint16_t low) { return (high << 16) | low; } That is endian agnostic.
