* * Institute a hack for the Sparc call to mmap() to get our generated code to beMisha Brukman2003-06-041-10/+16
| | | | | | | | | | | laid out closer to the VM so that calls to library functions (e.g. puts()) and callback (e.g. JITResolver::CompilationCallback) fit into 30 bits of the call instruction. * Abort if architecture is not yet supported (not X86 or Sparc) because it likely requires a different set of parameters to mmap() . * Stop using hard-coded values for page size; use sysconf(_SC_PAGESIZE) instead. llvm-svn: 6610
* Make writeNumber() void. Get ready to decouple it from .byte directive output.Brian Gaeke2003-06-041-4/+9

In the second case, it is already a constant, but then if it doesn't change its type (e.g. to become a register and have the value loaded from memory if it is too large to live in its instruction field), we must change the opcode BEFORE the 'continue', otherwise we miss the opportunity. llvm-svn: 6602
