From 1ec19679b3db209429b0897f6ccda6d09d018a70 Mon Sep 17 00:00:00 2001 From: mrb0nk500 Date: Sat, 8 Aug 2020 10:28:36 -0400 Subject: Did a ton of stuff. - Changed the file structure of the SuB Suite, so that all variable declarations, symbols, and constants are in a single file. - Moved the C library functionss into a separate file, and made them use stack frames. - Added support for using the emulator's assembler for realtime debugging, to enter it, get in to stepping mode by pressing Ctrl+s, press any other key, then press F1, The reason for having to press some other key before pressing F1 is because it only allows entering the assembler when the keyboard is not ready. - Added the ".res" directive to the emulator's assembler, the ".res" directive tells the assembler to reserve however many bytes specified by the operand. - Fixed some bugs in the emulator's assembler. --- asmmon.c | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'asmmon.c') diff --git a/asmmon.c b/asmmon.c index 5bc1993..1ad8d98 100644 --- a/asmmon.c +++ b/asmmon.c @@ -17,7 +17,9 @@ uint16_t incl[MAX_TOK]; line *lines; line *last_line; symbol *symbols = 0; +symbol *last_sym = 0; fixup *fixups = 0; +fixup *last_fix = 0; static char tstr[2048]; @@ -110,7 +112,7 @@ char *showbits(uint64_t value, uint8_t bitnum, uint8_t dbg) { } -void list(uint16_t start, uint16_t end, uint8_t all, uint8_t ln, uint8_t addr, uint8_t dbg) { +void list(uint16_t start, uint16_t end, uint8_t all, uint8_t ln, uint8_t addr, uint64_t address, uint8_t dbg) { line *s = (!all) ? find_line(start, dbg) : lines ; line *e = (!all) ? find_line( end, dbg) : last_line; uint8_t j = 0; @@ -125,8 +127,8 @@ void list(uint16_t start, uint16_t end, uint8_t all, uint8_t ln, uint8_t addr, u uint8_t tabs; char mne_lower[4]; char ch[6]; - do { + address = s->addr; token *t = s->tok; uint8_t am = 0xFF; uint8_t rs = 0xFF; @@ -174,6 +176,12 @@ void list(uint16_t start, uint16_t end, uint8_t all, uint8_t ln, uint8_t addr, u case INDY: putchar('('); break; } break; + case TOK_OF: + switch (t->type) { + case 1: printf("sp"); break; + case 2: printf("pc"); break; + } + break; case TOK_SYM: case TOK_LABEL: if (t->type == 1) { @@ -436,9 +444,9 @@ int asmmon(const char *fn) { } i++; } - list(start, end, isstart, islinenum, isaddr, isdebug); + list(start, end, isstart, islinenum, isaddr, 0, isdebug); } else { - list(0, 0, 1, 0, 0, 0); + list(0, 0, 1, 0, 0, 0, 0); } break; case 0x08: @@ -447,6 +455,7 @@ int asmmon(const char *fn) { } if (!inc_file) { puts("Now assembling."); + address = 0; bc.progsize = 0; bc.datasize = 0; assemble(lines, &bc, dbg); -- cgit v1.2.3-13-gbd6f
