bytecode multiple output significantly, but this way handles generating relocations correctly (otherwise extern foo; times 5 dd foo doesn't work!). * bytecode.h (yasm_bc_tobytes): Remove multiple output parameter. (yasm_bc_get_multiple): New. * bytecode.c (yasm_bc_tobytes): Update to iterate through multiple here. (yasm_bc_get_multiple): New. * xdf-objfmt.c, elf-objfmt.c, bin-objfmt.c, coff-objfmt.c: Don't iterate through multiple here. * nasm-listfmt.c: Use yasm_bc_get_multiple() to get multiple instead of yasm_bc_tobytes(). * bytecode.pxi: Update. * tests/win32-relocovfl.asm: Tests both this and [1534] but generates too huge of a file (3MB) to be put into the automated tests. svn path=/trunk/yasm/; revision=1536
