2024-08-12perf tool: Move fill defaults into tool.cIan Rogers5-311/+331
The aim here is to eventually make perf_tool__fill_defaults() an init function so that the tools struct is more const. Create a tool.c to go along with tool.h. Move perf_tool__fill_defaults() out of session.c into tool.c along with the default stub values. Add perf_tool__compressed_is_stub() for a test in perf_session__process_user_event(). perf_session__process_compressed_event() is only used from being default initialized so migrate into tool.c.

2024-08-10tools/nolibc: powerpc: limit stack-protector workaround to GCCThomas Weißschuh1-1/+1
As mentioned in the comment, the workaround for __attribute__((no_stack_protector)) is only necessary on GCC. Avoid applying the workaround on clang, as clang does not recognize __attribute__((__optimize__)) and would fail.

2024-08-10tools/nolibc: mips: load current function to $t9Thomas Weißschuh1-1/+3
The MIPS calling convention requires the address of the current function to be available in $t9. This was not done so far. For GCC this seems to have worked, but when compiled with clang the executable segfault instantly. Properly load the address of _start_c() into $t9 before calling it.

2024-08-10tools/nolibc: arm: use clang-compatible asm syntaxThomas Weißschuh1-2/+2
The clang assembler rejects the current syntax. Switch to a syntax accepted by both GCC and clang. Acked-by: Willy Tarreau <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Thomas Weißschuh <[email protected]>
