/Bmmemavailable
Use the /Bm option to increase the amount of memory that is available to the compiler during its second pass. Use of this option is necessary only if you encounter the “Function too large to optimize” error message. The default memory limit that the compiler works within is 2048K. The memavailable argument accepts the new amount (in kilobytes) of memory; thus a memavailable value of 4096 makes 4 megabytes of memory available. A space between /Bm and memavailable is optional.
