Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
Adds conditional exports
- __fixkfti
- __fixunskfti
- __floattikf
- __negkf2
- __mulkc3
- __divkc3
- __powikf2
and adjusts tools/gen_stubs.zig.
From https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html:
"When long double transitions to __float128 on PowerPC in the future,
__ibm128 will remain for use in conversions between the two types."
Hence `__extendkftf2` and `__trunctfkf2` for conversion are superfluous
and only using f128 for `kf` routines is justified.
Closes#16057.
* CompileStep: Avoid calling producesPdbFile() to determine whether the
option should be respected. If the user asks for it, put it on the
command line and let the Zig CLI deal with it appropriately.
* Make the namespace of `std.dwarf.Format.dwarf32` no longer have a
redundant "dwarf" in it.
* Add `zig cc` integration for `-gdwarf32` and `-gdwarf64`.
* Toss in a bonus bug fix for `-gdwarf-2`, `-gdwarf-3`, etc.
* Avoid using default init values for struct fields unnecessarily.
* Add missing cache hash addition for the new option.
Previously they were strong aliases, but as these types are used quite
intermittendly it resulted in a lot of toRef() calls. Removing them
improves readability a bit.
This makes -r treated the same as -c which is to output an object file.
Zig's ELF linker code already handles multiple object files into an
object file with the -r flag to LLD.
closes#11683
Also clean up parsing of linker args - reuse `ArgsIterator`.
In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.
MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.
Partial revert of 1e963053d0. Now that
lldb has a new method for accessing this data that does not require
manual updating, there is no longer any reason to share this data.
- Copy and adjust __divmodsi4 tests for __divmoddi4 and __divmodti4.
- Assuming d = a/b does not overflow (MIN/-1) or uses div by 0,
then tmp = (d * b) = (a/b * b) = a does not overflow.
=> Remove wraparound for remainder in applicable routines.
These are unused in LLVM, but in gcc used for example by rl78.
Move test files into common file, add tests for aforementioned routines
and missing ones for __lshrti3.
Commit 40f5e5dfc6 ("CLI: introduce -fsingle-threaded/
-fno-single-threaded", 2021-12-01) removed the `--single-threaded`
option, but didn't update all mentions of it.
