I'm afraid I have no better ideas than the ones tha= t you have listed - and in fact I wouldn=E2=80=99t have known about those o= nes either. I was just curious about what the next step would be. It certainly seems to me like an interesting and worthwhile project.=C2=A0 Best wishes - Neil=C2=A0 =C2=A0 Original Message =C2=A0 From: Jan Nieuwenhuizen Sent: Monday, 26 June 2017 11:22 To: Neil Jerram Cc: guile-user@gnu.org; guix-devel@gnu.org; epsilon-devel@gnu.org Subject: Re: Mes 0.8 released Neil Jerram writes: Hi Neil! > In your bootstrap path, what is the step after Mes?=E2=80=8E I guess it w= ould > be using mescc to compile some C program - but if that is right, which > program?=C2=A0 Indeed. Short answer: I don't know. Do you have something in mind? We haven't decided yet and are still exploring possibilities. We are looking for the target that requires the least amount of work to get us close the bootstrap path to gcc. The most obvious candidate to compile with mescc is tinycc. rain1 has worked with the tinycc and succeeded in compiling GCC 4.7.0 using tinycc[0]. However, tinycc uses C constructs that mescc does not support [yet] and libc functions that mescc's libc does not have. So we are also considering other candidates such as 8cc, pcc, the ack, cc500, gcc-2.95 (what about earlier gcc's?). Another possible first target for Mescc could be libguile/eval.c ;-) and develop a fork/sister of mescc as guilecc.
