compiler_rt: Add missing `f16` functions This change also exposes some of the existing functions under both the PPC-style names symbols and the compiler-rt-style names, since Zig currently lowers softfloat calls to the latter. 2022-10-07 18:19:08 +01:00			`const common = @import("common.zig");`

compiler-rt: Set the symbol visibility When we're compiling compiler_rt for any WebAssembly target, we do not want to expose all the compiler-rt functions to the host runtime. By setting the visibility of all exports to `hidden`, we allow the linker to resolve the symbols during linktime, while not expose the functions to the host runtime. This also means the linker can properly garbage collect any compiler-rt function that does not get resolved. The symbol visibility for all target remains the same as before: `default`. 2022-12-28 13:57:17 +00:00			`@export(__divhf3, .{ .name = "__divhf3", .linkage = common.linkage, .visibility = common.visibility });`
