<ccx>Noted. Thanks again. :−) <stikonas>hmm, riscv64 assembler in tcc is very primitive... <stikonas>it doesn't even know about jal instruction <muurkha>hmm, does that mean you don't have subroutines? <stikonas>compiler emits jumps directly using binary opcodes <stikonas>even cc_*, M2, mescc compilers have clear separation between compiling and assembling <stikonas>and of course tcc riscv64 assembler has syntax that is incompatible with gcc <stikonas>I guess that's no different from our early M1 based compilers <stikonas>but it will make it hard to build any C library <muurkha>I think it's pretty common to write compilers that emit machine code directly instead of textual assembly, just not on Unix <oriansj>muurkha: well it is much easier to write compilers that emit text than compilers that have to deal with the ugly low level bit encoding details. <oriansj>It just happens to have the added benefit of being easier to debug and reason about <muurkha>hmm, I've done both, but maybe not enough to have an informed opinion <muurkha>I feel like maybe which is easier might depend on how fast the compiler has to go <muurkha>and maybe also how much diversity of instruction formats you have <oriansj>well that is entirely valid, if one doesn't need to do optimizations (like M2-Planet) doing 1MLoC/second isn't a hard target on modern hardware. <oriansj>and supporting dozens of architectures really quickly explodes the number of bits your compiler has to know and embed. <muurkha>the particular thing I'm procrastinating on right now is a very simple compiler and bytecode interpreter with some tricky parts, pretty similar to Smalltalk-80 in some ways <kerravon>hello. i saw a bootstrappable wiki where the author says he prefers to enter the boot sector in using switches. i wasn't aware that there were computers still sold that have switches. <kerravon>1) A sub 500 byte hex monitor [How you create it is up to you; I like toggling it in manually myself] <stikonas[m]>kerravon: no there are no computers made with switches, you would have to make one yourself <pabs3>they left before your answer stikonas[m] <oriansj>but perhaps kerravon will look at the logs and realize not everyone lives in the same timezone
