delta/lua-github.git/lcode.c, branch temporary github.com: lua/lua.git Fixed "conceptual" bug in 'luaK_setreturns' 2020-03-02T16:24:06+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2020-03-02T16:24:06+00:00 e4607523234f16ed9ed0436340b9315377dbfe7f This function was computing invalid instruction addresses when the expression was not a multi-return instruction. (Virtually all machines don't raise errors when computing an invalid address, as long as the address is not accessed, but this computation is undefined behavior in ISO C.)

LUA_T* represents only types; tags (types + Variants) are represented
by LUA_V* constants.

Instead of an explicit value (field 'b'), true and false use different
tag variants. This avoids reading an extra field and results in more
direct code. (Most code that uses booleans needs to distinguish between
true and false anyway.)
