Andy Wingo e5dc27b86d increase range of relative jumps by aligning blocks to 8-byte boundaries ... * libguile/objcodes.c (OBJCODE_COOKIE): Bump again, as our jump offsets are now multiplied by 8. * libguile/vm-i-system.c (BR): Interpret the 16-bit offset as a relative jump to the nearest 8-byte-aligned block -- increasing relative jump range from +/-32K to +/-240K. (mvra): Do the same for the mvra jump. * libguile/vm.c (really_make_boot_program): Align the mvra. * module/language/assembly.scm (align-block): New export, for aligning blocks. * module/language/assembly/compile-bytecode.scm (write-bytecode): Emit jumps to the nearest 8-byte-aligned block. Effectively our range is 18 bits in either direction. I would like to do this differently -- have long-br and long-br-if, and all the other br instructions go to 8 bits only. But the assembler doesn't have an appropriate representation to allow me to do this yet, so for now this is what we have. * module/language/assembly/decompile-bytecode.scm (decode-load-program): Decode the 19-bit jumps.		2009-07-26 14:01:56 +02:00
