Does your arch's compiler support -ffuncation-sections and -fdata-sections? As well as your linker supporting --gc-sections ? All the architectures we support have those flags. See Makefile.inc which provides those in CFLAGS_common and LDFLAGS_common. That support allows us to not sprinkle #ifdef's all around in the code when the same source file is compiled for different stages. > > > -------- Original Message -------- > Subject: Re: [coreboot] Some errors by compiling romstage (I am a newbie) > Local Time: 2 Марта 2017 г. 5:22 вечера > UTC Time: 2 Марта 2017 г. 14:22 > From: [email protected] > To: Maxim Gusev <[email protected]> > [email protected] <[email protected]> > > On Thu, Mar 2, 2017 at 7:24 AM, Maxim Gusev via coreboot > <[email protected]> wrote: >> Hi everbody! >> >> I have a question.
