- fixup 128-bit atomics test to only run on x86_64
- add truncation test for 128-bit types, including non power of two targets (there was a bug with broken non-power-of-two truncation in the cbe)
- add 128-bit binary not test (covers another bug fixed in the cbe)
Rather than checking for function pointers during the writing phase,
we now create a synethtic symbol when a new link job has started.
This means the symbol can correctly be resolved during link time
with the indirect function table from other object files, ensuring
we are properly performing relocations and our binary writer is now
unaware of any of its logic and simply emits the table according to
the symbol such as any other symbols.
Adds a linker test case for each possible export case. This means
one where no exports are done (i.e. no flags set), when the -dynamic
flag is set, and finally when --export=<value> flag(s) are set.
Adds support for both the `-rdynamic` and the `--export=<value>`
flags. Support is added to both the incremental linker as well as
the traditional linker (zld).
- Add cpuid / getXCR0 functions for the cbe to use instead of asm blocks
- Don't cast between 128 bit types during truncation
- Fixup truncation to use functions for shifts / adds
- Fixup float casts for undefined values
- Add test for 128 bit integer truncation
- Fix zig_clz_u128 not respecting the bits argument. This was crashing the compile-rt addxf3 tests with the cbe
- Instead of redering a negation for negative 128 bit int literals, render the literal as twos complement. This allows
rendering int representations of floats correctly (specifically f80).
- Add .StaticInitializer to ValueRenderLocation to indicate that the emitted values
must be constant expressions (no function calls, struct casting).
- Add new path for special float types (nan, inf) that works in constant expressions
- Implement windows.teb() using a syscall for .stage2_c because x64 MSVC
doesn't support any kind of inline asm
- Map the __builtin_nan(f|l)? functions to nan(f|l)? on msvc
- MSVC throws C2099 when initializing a struct with cast syntax
in a global initializer. Added zig_as_init_ to handle this case,
and generate it only in static initializers for > 64 bit ints.
- Change float initialization to emit the integer representation
in global initializers to avoid C2099 caused by calling nan.
