Subject: ELF: Make sure the macro generater the correct value
X-Git-Tag: v1.2~14
X-Git-Url: https://git.htl-mechatronik.at/public/?a=commitdiff_plain;h=fde567e3803f69614948b937c14184e0b6a0f308;p=sx%2Fsimavr.git

ELF: Make sure the macro generater the correct value

You could pass constants over 8 bits in size, generating very confusing
values
