From dcedb70a5ccead41574cf857b369d264c87dd7e0 Mon Sep 17 00:00:00 2001 From: Aryadev Chavali Date: Sat, 21 Oct 2023 22:57:43 +0100 Subject: Switched from floats to halfword Registers are now just words, with pushing from and moving to registers with specified subtypes just pushing those types into the word registers. That means there are 8 word registers which can act as 16 half word registers, which themselves can act as 64 byte registers. --- src/base.h | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) (limited to 'src/base.h') diff --git a/src/base.h b/src/base.h index 670aa81..e8ddfdb 100644 --- a/src/base.h +++ b/src/base.h @@ -26,27 +26,29 @@ typedef float f32; typedef double f64; typedef uint8_t byte; +typedef u32 hword; typedef u64 word; typedef union { byte as_byte; + hword as_hword; word as_word; - f64 as_float; } data_t; typedef enum { - DATA_TYPE_NIL = 0, - DATA_TYPE_BYTE = 1, - DATA_TYPE_WORD = 3, - DATA_TYPE_FLOAT = 5, + DATA_TYPE_NIL = 0, + DATA_TYPE_BYTE, + DATA_TYPE_HWORD, + DATA_TYPE_WORD, } data_type_t; #define DBYTE(BYTE) ((data_t){.as_byte = (BYTE)}) +#define DHWORD(HWORD) ((data_t){.as_hword = (HWORD)}) #define DWORD(WORD) ((data_t){.as_word = (WORD)}) -#define DFLOAT(FLOAT) ((data_t){.as_float = (FLOAT)}) +#define HWORD_SIZE sizeof(hword) #define WORD_SIZE sizeof(word) #define FLOAT_SIZE sizeof(f64) -- cgit v1.2.3-13-gbd6f
