- Enable LTO on x64 (Tumbleweed and Fedora only) now that it works correctly. * add seccomp_pbf-no-lto.patch - Do not build some chromium features unused in Electron. - Remove upstream's tinkering with optimization flags. * change chromium-102-compiler.patch - Remove upstream's warning suppression * change chromium-102-compiler.patch * add -Wno-class-memaccess due to log spam * add -Wno-error=narrowing due to non-compliant generated code - Add -DIS_SERIAL_ENABLED_PLATFORM to work around upstream C++ ODR error. - Build main binary as PIE instead of PIC. * change chromium-102-compiler.patch * add fpic.patch - Compile with gcc11 (was 10) on Leap now that it's available. - Add backported patches * compact_enc_det_generated_tables-Wnarrowing.patch * half_float-Wstrict-aliasing.patch * ipcz-buffer_id-Wnarrowing.patch * select_file_dialog_linux_kde-Wodr.patch * string_hasher-type-pun-UB-causes-heap-corruption.patch * unzip-Wsubobject-linkage.patch * web_contents_impl-Wsubobject-linkage.patch - Add patches to fix C++ bugs and submit them upstream * swiftshader-Constants-Wstrict-aliasing.patch * swiftshader-Half-Wstrict-aliasing.patch * v8_initializer-PageAllocator-fpermissive.patch OBS-URL: https://build.opensuse.org/request/show/1031228 OBS-URL: https://build.opensuse.org/package/show/devel:languages:nodejs/nodejs-electron?expand=0&rev=42
