Speculation occurs when a conditionally executed instruction is moved to a position before a test instruction so that the moved instruction is then executed unconditionally. Strictly enforces the ANSI C standard and all its prohibitions. Directs the linker to load the executable file in the lower 31-bit addressable virtual address range. The maximum number of iterations to unroll inner loops. The maximum work allowed in an unrolled loop.
Work is estimated by counting operands and operators in a loop.
The lower limit for unrolling. If there are less than n units of work in the loop, the loop will not be unrolled. Directs the compiler to allocate 32-bit pointers by default. You can still use 64-bit pointers, but only by the use of pragmas.
