I wouldn't think so. If you remove that option does it magically work? From the errors you showed -gc-sections along with -fdata-sections and -ffunction-sections would have removed the unreferenced symbols and not cause a link error. To prove that -f(data|function)-sections are working can you provide the readelf -e output from an intermediate .o file you compiled for romstage? > > > > -------- Original Message -------- > Subject: Re: [coreboot] Some errors by compiling romstage (I am a newbie) > Local Time: 2 Марта 2017 г. 6:01 вечера > UTC Time: 2 Марта 2017 г. 15:01 > From: [email protected] > To: Maxim Gusev <[email protected]> > [email protected] <[email protected]> > > On Thu, Mar 2, 2017 at 8:33 AM, Maxim Gusev <[email protected]> wrote: >> Hello, Aaron! >> >> I am compiling sourses of my arch e2k. >> I have compiled bootblock with my sources.
