Inter-architecture compatability module to allow code module of one architecture to use library module of another architecture

An inter-architecture compatibility method that is executable by a processor comprising:

• receiving a first call procedure operation intended for a first X-bit architecture library module, which is compatible with an X-bit architecture processor, from a first X-bit architecture code module that is to be running on a Y-bit architecture processor, by using function inter-positioning where a wrapper library is searched before a first X-bit architecture library is searched, and where a first wrapper module having a same name as the first X-bit architecture library module is identified before the first X-bit architecture library module, the first call procedure operation involving a first plurality of input parameters, wherein the first X-bit architecture library module is one of a C standard library module, a math library module, a glibc module, and a system library module;
• making application binary interface (ABI) changes to convert the first call procedure operation involving the first plurality of input parameters to a corresponding second call procedure operation involving a second plurality of input parameters and that is compatible with a second Y-bit architecture library module, which is compatible with the Y-bit architecture processor, wherein Y is greater than X;
• and
• providing the second call procedure operation to the second Y-bit architecture library module, which is compatible with the Y-bit architecture processor on which the first X-bit architecture code module is running.

A computer system comprising:

• a memory to store a 32-bit code module, a 64-bit library module, and a 64-bit operating system module;
• a 64-bit processor coupled with the memory;
• and
• an inter-architecture compatibility module that is one or more of (a) included on a die of the 64-bit processor and (b) stored in the memory to intercept through function inter-positioning a call procedure operation from the 32-bit code module which is to be run on the 64-bit processor for a 32-bit library module, which is to be one of a C standard library module, a math library module, a glibc module, and a system library module, wherein in the function inter-positioning a wrapper library is to be searched before a 32-bit library is searched, and a first wrapper module has a same name as the 32-bit library module is to be identified before the 32-bit library module, and the inter-architecture compatibility module to provide a corresponding call procedure operation to the 64-bit library module, which is to be compatible with and is to be run on the 64-bit processor;
• wherein the inter-architecture compatibility module is to make application binary interface (ABI) changes to convert the call procedure operation for the 32-bit library module to the corresponding call procedure operation for the 64-bit library module;
• and
• wherein the 32-bit code module and the 64-bit library module are to be stored in different segments in the memory, and wherein a segment that is to store the 32-bit code module is to use flat addressing.

An article of manufacture comprising a non-transitory machine-readable storage medium that stores instructions that, executed by a processor of a computer system, cause the processor to perform operations including to:

• receive through function inter-positioning a first call procedure operation intended for a first X-bit architecture library module, which is to be compatible with an X-bit architecture processor, from a first X-bit architecture code module that is to be running on a Y-bit architecture processor, wherein in the function inter-positioning a wrapper library is to be searched before a first X-bit architecture library is searched, and where a first wrapper module has a same name as the first X-bit architecture library module is to be identified before the first X-bit architecture library module, the first call procedure operation involving a first plurality of input parameters, wherein the first X-bit architecture library module is one of a C standard library module, a math library module, a glibc module, and a system library module;
• make application binary interface (ABI) changes to convert the first call procedure operation involving the first plurality of input parameters to a corresponding second call procedure operation involving a second plurality of input parameters;
• and
• provide the second call procedure operation to a second Y-bit architecture library module, which is to be compatible with the Y-bit architecture processor on which the first X-bit architecture code module is to be running, wherein Y is greater than X.
