Full name of some variable and function names

[JavanZhu]

1. In file ems_kfc.c, what is the full name of "ems" and "kfc"?
2. And in "read_leb", what is the full name of "leb"?
   

   wasm-micro-runtime/core/iwasm/interpreter/wasm_loader.c

   Lines 87 to 96 in fda3a26

   	static bool
   	read_leb(uint8 **p_buf, const uint8 *buf_end,
   	uint32 maxbits, bool sign, uint64 *p_result,
   	char* error_buf, uint32 error_buf_size)
   	{
   	const uint8 *buf = *p_buf;
   	uint64 result = 0;
   	uint32 shift = 0;
   	uint32 offset = 0, bcnt = 0;
   	uint64 byte;

3. In "frame_ip", not sure the full name of "ip" whether is the "instruction pointer", and some other similar variable names like "frame_lp", "frame_sp", "frame_csp" in the same function, also curious about the full name of "lp" and "sp" and "csp".
   

   wasm-micro-runtime/core/iwasm/interpreter/wasm_interp_classic.c

   Lines 1086 to 1089 in fda3a26

   	register uint8 *frame_ip = &opcode_IMPDEP; /* cache of frame->ip */
   	register uint32 *frame_lp = NULL; /* cache of frame->lp */
   	register uint32 *frame_sp = NULL; /* cache of frame->sp */
   	WASMBranchBlock *frame_csp = NULL;

please tell me if anyone knows, thank you very much.

1. Sorry, I don't know too.
2. "leb" is "leb128", "Little Endian Base 128".
3. frame_ip is "instruction pointer".frame_sp is "stack pointer".frame_lp is probably "local pointer".I don't know csp,sorry.

I wanna know what is the full name of "hmu" and "gc".

Hi @kan-fumihito, Thanks for your reply. The full name of "hmu" is "heap memory unit" which could be referenced at

wasm-micro-runtime/core/shared/mem-alloc/ems/ems_gc_internal.h

Lines 14 to 17 in 6b3a939

	#include "ems_gc.h"
	/* HMU (heap memory unit) basic block type */
	typedef enum hmu_type_enum {

and maybe the "gc" is abbreviation of "garbage collection".
