The goal of this project is to automatically generate the stack comments.
From this:
#define macro SET_VALUE2() = takes (2) returns (0) {
0x04
0x04
_XXX_YYY
0x04
0x55
lt
0x87
gt
}
#define macro _XXX_YYY() = takes (1) returns (1) {
0x06
calldataload
[VALUE_LOCATION]
sstore
0x69
0x00
}
To this:
#define macro SET_VALUE2() = takes (2) returns (0) {
0x04 // [$0, $1, 0x04]
0x04 // [$0, $1, 0x04, 0x04]
_XXX_YYY // [$0, $1, 0x04, _XXX_YYY: %0]
0x04 // [$0, $1, 0x04, _XXX_YYY: %0, 0x04]
0x55 // [$0, $1, 0x04, _XXX_YYY: %0, 0x04, 0x55]
lt // [$0, $1, 0x04, _XXX_YYY: %0, (0x55 < 0x04)]
0x87 // [$0, $1, 0x04, _XXX_YYY: %0, (0x55 < 0x04), 0x87]
gt // [$0, $1, 0x04, _XXX_YYY: %0, (0x87 > (0x55 < 0x04))]
}
#define macro _XXX_YYY() = takes (1) returns (1) {
0x06 // [$0, 0x06]
calldataload // [$0, calldataload(0x06)]
[VALUE_LOCATION] // [$0, calldataload(0x06), [VALUE_LOCATION]]
sstore // [$0]
0x69 // [$0, 0x69]
0x00 // [$0, 0x69, 0x00]
