It seems corona-chan has finally taken my body. I felt like death for two days, but now if I were to complain it would basically just be whinging. I understand there are many regional variants and different personal situations. For those two days though, I slept fitfully and was a bit delerious. I only developed a bit of phlegm now that I am basically better (I have sequestered myself to protect others to the extent possible). But! Enough about me. I feel like it's been a while since I just made a long sequence of posts that are just me reading nm03's phloging. By the way, nm03 (doubtless also reading my phlog), given the systematic layout of your phlog I thought it might be interesting if you added a gopher cgi to search particular time ranges or something. The web link on peteyboy's phlog saying that it's ecumenically forbidden seems to be dead to me. I do recall that /ftp/pub/gopher-tutorial.txt seemed out of date, and what helped me a lot was gopher://sdf.org/0/users/yargo/scripts/chag.sh The current post as of me writing talks about how GNU-cobol produces C, and what that means viz compilation. As I attempted to write this post in my corona-delerium I realised it is a modestly subtle topic. I will make a follow-up part ii post tomorrow-ish. What follows is some trivial disassembly from different lisp compilers specifically under 'compile and not 'compile-file, which do different things in lisp. I'm going to take a rest. $ ecl > (ext:install-bytecodes-compiler) > (disassemble (lambda () (print 'foo))) Name: NIL 0 NOMORE 1 PUSH 'FOO 3 CALLG 1,PRINT 6 EXIT > (ext:install-c-compiler) (disassemble (lambda () (print 'foo))) /* function definition for GAZONK */ /* optimize speed 3, debug 0, space 0, safety 2 */ static cl_object L1c__gazonk() { cl_object env0 = ECL_NIL; const cl_env_ptr cl_env_copy = ecl_process_env(); cl_object value0; ecl_cs_check(cl_env_copy,value0); { TTL: value0 = ecl_print(VV[1],ECL_NIL); cl_env_copy->nvalues = 1; return value0; } } But sbcl does not go via C: * (disassemble (lambda () (print 'foo))) ; disassembly for (lambda ()) ; I elided some stuff/memory addresses. ; MOV RAX, [R13+16] ; MOV [RBP-8], RAX ; MOV RDX, [RIP-67] ; 'FOO ; MOV ECX, 2 ; PUSH QWORD PTR [RBP+8] ; MOV EAX, #x.. ; # ; JMP RAX ; INT3 16 ; trap
