Yeah, I just noticed a.out. Is there a way to prevent SCons from producing it? Which copyright information are you referring to? I went through and added it where I thought it was necessary, but I'm not very familiar with copyrights and licensing so I could have gotten it wrong. I have tried running the some of the RISC-V tests, but they don't seem have the structure that GEM5 expects--for example, the entry point of rv64ui-p-add as defined by the ELF file doesn't exist in the disassembly. > On Sept. 15, 2016, 2:50 p.m., Jason Lowe-Power wrote: > > ext/libelf/elf_common.h, line 176 > > <http://reviews.gem5.org/r/3624/diff/1/?file=57831#file57831line176> > > > > It would be nice if this were aligned with the above. Do you mean the two lines immediately preceding it? It is aligned with most of the other EM definitions. - Alec ----------------------------------------------------------- This is an automatically generated e-mail.
