rustc: Add an option to default hidden visibility This commit adds a new option to target specifictions to specify that symbols should be "hidden" visibility by default in LLVM. While there are no existing targets that take advantage of this the `wasm32-unknown-unknown` target will soon start to use this visibility. The LLD linker currently interprets `hidden` as "don't export this from the wasm module" which is what we want for 90% of our functions. While the LLD linker does have a "export this symbol" argument which is what we use for other linkers, it was also somewhat easier to do this change instead which'll involve less arguments flying around. Additionally there's no need for non-`hidden` visibility for most of our symbols! This change should not immediately impact the wasm targets as-is, but rather this is laying the foundations for soon integrating LLD as a linker for wasm code. |
