Source: webkit2gtk Version: 2.26.4-1 Severity: normal Tags: patch User: [email protected] Usertags: sh4 Hi! In order for webkit2gtk to build on sh4, it's necessary to enable the new register allocator on sh4 (LRA), see [1, 2]. Also, there is a regression in gcc-9 and gcc-10 that needs one optimization to be disabled as otherwise the compiler will crash with an internal compiler error (ICE) [3]. Please apply the attached patch for the next upload. Thanks, Adrian > [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55212 > [2] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93876 > [3] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93877 -- .''`.
