Abstract
Compiling code for an enhanced application binary interface (ABI) including identifying, by a computer, a code sequence configured to perform a variable address reference table function including an access to a variable at an offset outside of a location in a variable address reference table. The code sequence includes an internal representation (IR) of a first instruction and an IR of a second instruction. The second instruction is dependent on the first instruction. A scheduler cost function associated with at least one of the IR of the first instruction and the IR of the second instruction is modified. The modifying includes generating a modified scheduler cost function that is configured to place the first instruction next to the second instruction. An object file is generated responsive to the modified scheduler cost function. The object file includes the first instruction placed next to the second instruction. The object file is emitted.
