For SPIR-V, only export the main function if it is actually declared. Kernel
entry points will often have parameters and more than one kernel declared.
In general, SPIR-V binaries should mostly be compiled as libraries and not as
executables. However, this start code is required so that we can build test
executables.
Note that a call to isSpirV() would emit the code for that function, even though
the call is at comptime. To save that function from being emitted the checks
are just inlined manually.
AmdgpuKernel and NvptxKernel are unified into a Kernel calling convention.
There is really no reason for these to be separate; no backend is allowed to
emit the calling convention of the other. This is in the same spirit as the
.Interrupt calling convention lowering to different LLVM calling conventions,
and opens the way for SPIR-V kernels to be exported using the Kernel calling
convention.
This adds a general target for SPIR-V compilation. Previously there was not
any target machine defined for SPIR-V.
TODO is to reword the features for this target. We don't really need the full
list of capabilities in the features, we should only put a few features here
which we can actually use during code generation.
* GPA: Catch invalid frees
Fix#14791: Catch cases where an invalid slice is passed to free().
This was silently ignored before but now logs an error. This change
uses a AutoHashMap to keep track of the sizes which seems to be an
overkill but seems like the easiest way to catch these errors.
* GPA: Add wrong alignment checks to free/resize
Implement @Inkryption's suggestion to catch free/resize with the wrong
alignment. I also changed the naming to match large allocations.
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.
Notably the Darwin (XNU) kernel the maxrss field is number of bytes
and not kilobytes (kibibytes) like other platforms (e.g. Linux, BSD).
watchOS and tvOS are not supported because they do not have the ability
to spawn a child process. iOS is enabled but due to OS sandboxing it
should fail with a permission error.
