Prior to this change we would assume the ABI for Apple targets to be GNU which could result in subtle errors in LLVM emitting calls to non-existent system libc provided functions such as `_sincosf` which is a GNU extension and as such is not provided by macOS for example. This would result in linker errors where the linker would not be able to find the said symbol in `libSystem.tbd`. With this change, we now correctly identify macOS (and other Apple platforms) as having ABI `unknown` which translates to unspecified in LLVM under-the-hood: ``` // main.ll target triple = "aarch64-unknown-macos-unknown" ``` Note however that we never suffix the target OS with target version such as `macos11` or `macos12` which means we fail to instruct LLVM of potential optimisations provided by the OS such as the availability of function `___sincosf_stret`. I suggest we investigate that in a follow-up commit.

|
|
* When declaring new sysctl names, use the CTLFLAG_LOCKED flag in the

|
|
* Any sysctl defined without CTLFLAG_LOCKED is considered legacy

* yourself, if you are able to do so. A simple design
|

* pattern for use to avoid in a single function known

* unlock

* SYSCTL_OUT(rey, local buffer, length)

|
|
* ...this assumes you are not using a deep call graph
|
|
* or are unable to pass a local buffer address as a
|
|
* parameter into your deep call graph.
|
|
*
|
|
* Note that very large user buffers can fail the wire
|
|
* if to do so would require more physical pages than
|
|
* are available (the caller will get an ENOMEM error,
|
|
* see sysctl_mem_hold() for details).

/*
|
|
* XXX This information should be moved to the man page.
|
|
*
|
|
* These are the support HW selectors for sysctlbyname. Parameters that are byte counts or frequencies are 64 bit numbers.
|
|
* All other parameters are 32 bit numbers.
|
|
*
|
|
* hw.memsize - The number of bytes of physical memory in the system.
|
|
*
|
|
* hw.ncpu - The maximum number of processors that could be available this boot.
|
|
* Use this value for sizing of static per processor arrays; i.e. processor load statistics.
|
|
*
|
|
* hw.activecpu - The number of processors currently available for executing threads.
|
|
* Use this number to determine the number threads to create in SMP aware applications.
|
|
* This number can change when power management modes are changed.
|
|
*
|
|
* hw.physicalcpu - The number of physical processors available in the current power management mode.
|
|
* hw.physicalcpu_max - The maximum number of physical processors that could be available this boot
|
|
*
|
|
* hw.logicalcpu - The number of logical processors available in the current power management mode.
|
|
* hw.logicalcpu_max - The maximum number of logical processors that could be available this boot
|
|
*
|
|
* hw.tbfrequency - This gives the time base frequency used by the OS and is the basis of all timing services.
|
|
* In general is is better to use mach's or higher level timing services, but this value
|
|
* is needed to convert the PPC Time Base registers to real time.
|
|
*
|
|
* hw.cpufrequency - These values provide the current, min and max cpu frequency. The min and max are for
|
|
* hw.cpufrequency_max - all power management modes. The current frequency is the max frequency in the current mode.
|
|
* hw.cpufrequency_min - All frequencies are in Hz.
|
|
*
|
|
* hw.busfrequency - These values provide the current, min and max bus frequency. The min and max are for
|
|
* hw.busfrequency_max - all power management modes. The current frequency is the max frequency in the current mode.
|
|
* hw.busfrequency_min - All frequencies are in Hz.
|
|
*
|
|
* hw.cputype - These values provide the mach-o cpu type and subtype. A complete list is in <mach/machine.h>
|
|
* hw.cpusubtype - These values should be used to determine what processor family the running cpu is from so that
|
|
* the best binary can be chosen, or the best dynamic code generated. They should not be used
|
|
* to determine if a given processor feature is available.
|
|
* hw.cputhreadtype - This value will be present if the processor supports threads. Like hw.cpusubtype this selector
|
|
* should not be used to infer features, and only used to name the processors thread architecture.
|
|
* The values are defined in <mach/machine.h>
|
|
*
|
|
* hw.byteorder - Gives the byte order of the processor. 4321 for big endian, 1234 for little.
|
|
*
|
|
* hw.pagesize - Gives the size in bytes of the pages used by the processor and VM system.
|
|
*
|
|
* hw.cachelinesize - Gives the size in bytes of the processor's cache lines.
|
|
* This value should be use to control the strides of loops that use cache control instructions
|
|
* like dcbz, dcbt or dcbst.
|
|
*
|
|
* hw.l1dcachesize - These values provide the size in bytes of the L1, L2 and L3 caches. If a cache is not present
|
|
* hw.l1icachesize - then the selector will return and error.
|
|
* hw.l2cachesize -
|
|
* hw.l3cachesize -
|
|
*
|
|
* hw.packages - Gives the number of processor packages.
|
|
*
|
|
* These are the selectors for optional processor features for specific processors. Selectors that return errors are not support
|
|
* on the system. Supported features will return 1 if they are recommended or 0 if they are supported but are not expected to help .
|
|
* performance. Future versions of these selectors may return larger values as necessary so it is best to test for non zero.
|
|
*
|
|
* For PowerPC:
|
|
*
|
|
* hw.optional.floatingpoint - Floating Point Instructions
|
|
* hw.optional.altivec - AltiVec Instructions
|
|
* hw.optional.graphicsops - Graphics Operations
|
|
* hw.optional.64bitops - 64-bit Instructions
|
|
* hw.optional.fsqrt - HW Floating Point Square Root Instruction
|
|
* hw.optional.stfiwx - Store Floating Point as Integer Word Indexed Instructions
|
|
* hw.optional.dcba - Data Cache Block Allocate Instruction
|
|
* hw.optional.datastreams - Data Streams Instructions
|
|
* hw.optional.dcbtstreams - Data Cache Block Touch Steams Instruction Form
|
|
*
|
|
* For x86 Architecture:
|
|
*
|
|
* hw.optional.floatingpoint - Floating Point Instructions
|
|
* hw.optional.mmx - Original MMX vector instructions
|
|
* hw.optional.sse - Streaming SIMD Extensions
|
|
* hw.optional.sse2 - Streaming SIMD Extensions 2
|
|
* hw.optional.sse3 - Streaming SIMD Extensions 3
|
|
* hw.optional.supplementalsse3 - Supplemental Streaming SIMD Extensions 3
|
|
* hw.optional.x86_64 - 64-bit support
