Well its a hard requirement considering glibc is still using gcc-9 !

FWIW this change needs a pairing glibc change so must NOT be included for upcoming 2020.x release which still has old version of glibc ! -Vineet On 3/31/20 10:57 AM, Vineet Gupta wrote: > Well its a hard requirement considering glibc is still using gcc-9 ! > > Thx, > -Vineet > > On 3/31/20 9:26 AM, Alexey Brodkin wrote: >> Hi Claus, >> >>> -----Original Message----- >>> From: linux-snps-arc <linux-snps-arc-bounces@lists.infradead.org> On Behalf Of Claudiu Zissulescu >>> Ianculescu >>> Sent: Tuesday, March 31, 2020 1:07 PM >>> To: Vineet Gupta <vgupta@synopsys.com> >>> Cc: linux-snps-arc@lists.infradead.org; gcc-patches@gcc.gnu.org; Claudiu Zissulescu >>> <claziss@synopsys.com> >>> Subject: Re: [PATCH] [ARC] Allow more ABIs in GLIBC_DYNAMIC_LINKER >>> >>> Pushed. >> Is this one eligible for being back-ported to older GCCs? >> At least GCC 9.x would be really good. >> >> -Alexey >> > _______________________________________________ > linux-snps-arc mailing list > linux-snps-arc@lists.infradead.org > https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.infradead.org_mailman_listinfo_linux-2Dsnps-2Darc&d=DwICAg&c=DPL6_X_6JkXFx7AXWqB0tg&r=c14YS-cH-kdhTOW89KozFhBtBJgs1zXscZojEZQ0THs&m=xnl4FBxLN70UDZIvD2NTxyfPAenrfQsdij0DBuPImCI&s=YnG2GxYtFIbUU0FesR19TV7fz0ILe8xncKLnRiqBhOc&e=
Hi Claudiu, For glibc needs can this be backported to gcc-9 please !
