They both default to gnu, i.e. the\n> GNU Binutils toolchain or compatible assemblers and linkers.\n>\n> To deal with incompatible vendor toolchains, those variables can take\n> other values. In addition to solaris, there are aix, darwin, hpux, and\n> nvptx. More could be added as necessary.\n>\n> In preparation for the patch series above, this patch switches existing\n> code from solaris_{as,ld} to {as,ld}_flavor=solaris.\n>\n> It also checks the configured assembler and linker for the vendor\n> toolchains above. If there's a choice between native and GNU toolchains\n> (AIX, HP-UX, Solaris), the as and ld version outputs are examined.\n> Otherwise (Darwin, NVPTX), the values are hardcoded and only used in\n> configure messages.\n>\n> In addition to {as,ld}_flavor, HAVE__{AS,LD} macros are defined\n> in cases they are actually needed, matching existing HAVE_SOLARIS_{AS,LD}.\n>\n> Tested together with a reworked version of the patch series above on\n> x86_64-pc-linux-gnu, powerpc-ibm-aix7.3.1.0 (as/ld and gas/gld),\n> x86_64-apple-darwin17.7.0, i386-pc-solaris2.11 and sparc-sun-solaris2.11\n> (as/ld, gas/ld, and gas/gld). Also tested by Dave on HP-UX.\n>\n> For the time being, I've ignored VMS which would also need handling: the\n> support status of VMS support in GCC is completely unknown, AFAIK there\n> are no public build systems and there's no information on the targets in\n> install.texi.\n>\n> Ok for trunk?\n>\n\nOkay.\n\nThanks for adjusting the design.\n\nDavid\n\n\n>\n> Rainer\n>\n> --\n>\n> -----------------------------------------------------------------------------\n> Rainer Orth, Center for Biotechnology, Bielefeld University\n>\n>\n> 2026-05-03 Rainer Orth \n>\n> gcc:\n> * acinclude.m4: Check as_flavor, ld_flavor instead of solaris_as,\n> solaris_ld.\n> * configure.ac: Likewise.\n> (as_flavor, ld_flavor): New variables.\n> Adapt messages.\n> Set based on as, ld version output.\n> (HAVE_AIX_AS): Define.\n> * configure: Regenerate.\n> * config.in: Regenerate.\n>\n>","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","gcc-patches@gcc.gnu.org"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","gcc-patches@gcc.gnu.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=gmail.com header.i=@gmail.com header.a=rsa-sha256\n header.s=20251104 header.b=cJg45HNv;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=gcc.gnu.org\n (client-ip=2620:52:6:3111::32;
