2023-10-22tcg/ppc: Enable direct branching tcg_out_goto_tb with TCG_REG_TBJordan Niethe
Direct branch patching was disabled when using TCG_REG_TB in commit 736a1588c1 ("tcg/ppc: Fix race in goto_tb implementation"). The issue with direct branch patching with TCG_REG_TB is the lack of synchronization between the new TCG_REG_TB being established and the direct branch being patched in. If each translation block is responsible for establishing its own TCG_REG_TB then there can be no synchronization issue. Make each translation block begin by setting up its own TCG_REG_TB. Use the preferred 'bcl 20,31,$+4' sequence.

2023-09-29meson: clean up static_library keyword argumentsPaolo Bonzini
These are either built because they are dependencies of other targets, or not needed at all because they are used via extract_objects(). Mark them as "build_by_default: false"; if applicable, mark them as "fa" so that -Wl,--whole-archive does not interact with the linker script used for fuzzing. (The "fa" hack is brittle; updating to Meson 1.1 would allow using declare_dependency(objects: ...) instead).
