1.3 Binary Compatibility Verification

On Oracle Solaris systems, beginning with Sun Studio 11, program binaries compiled with the Oracle Developer Studio compilers are marked with architecture hardware flags indicating the instruction sets assumed by the compiled binary. At runtime, these marker flags are checked to verify that the binary can run on the hardware it is attempting to execute on.

Running programs that do not contain these architecture hardware flags on platforms that are not enabled with the appropriate features or instruction set extensions could result in segmentation faults or incorrect results occurring without any explicit warning messages.

This warning extends also to programs that employ .il inline assembly language functions or __asm() assembler code that use SSE, SSE2, SSE2a, and SSE3 and newer instructions and extensions.
