2000-06-19Use bfd_octets_per_byte instead of OCTETS_PER_BYTENick Clifton1-2/+2
2000-02-03octets vs bytes changes for GASTimothy Wall1-3/+3
2000-01-26This set of patches add support for aout emulation on the x86Alan Modra1-9/+15
assembler. ie. You will be able to do "as --em=i386aout" on an x86 linux-elf assembler to generate aout format object files, rather than using a separate assembler. The aout emulation is enabled by giving "--enable-targets=i386-linuxaout" to configure. Oh yeah, there's a couple of fixes too. Error messages shouldn't be passed to printf in the format arg just in case someone puts a `%' in the message.
