Functions§
- __
crc32b ⚠crc
CRC32 single round checksum for bytes (8 bits). - __
crc32cb ⚠crc
CRC32-C single round checksum for bytes (8 bits). - __
crc32cd ⚠crc
CRC32 single round checksum for quad words (64 bits). - __
crc32ch ⚠crc
CRC32-C single round checksum for half words (16 bits). - __
crc32cw ⚠crc
CRC32-C single round checksum for words (32 bits). - __
crc32d ⚠crc
CRC32 single round checksum for quad words (64 bits). - __
crc32h ⚠crc
CRC32 single round checksum for half words (16 bits). - __
crc32w ⚠crc
CRC32 single round checksum for words (32 bits). - __
arm_ ⚠mte_ create_ random_ tag Experimental mte
Return a pointer containing a randomly generated logical address tag. - __
arm_ ⚠mte_ exclude_ tag Experimental mte
Add a logical tag to the set of excluded logical tags. - __
arm_ ⚠mte_ get_ tag Experimental mte
Load an allocation tag from memory, returning a new pointer with the corresponding logical tag. - __
arm_ ⚠mte_ increment_ tag Experimental mte
Return a pointer with the logical address tag offset by a value. - __
arm_ ⚠mte_ ptrdiff Experimental mte
Calculate the difference between the address parts of two pointers, ignoring the tags, and sign-extending the result. - __
arm_ ⚠mte_ set_ tag Experimental mte
Store an allocation tag for the 16-byte granule of memory. - __dmb⚠
Experimental Generates a DMB (data memory barrier) instruction or equivalent CP15 instruction. - __dsb⚠
Experimental Generates a DSB (data synchronization barrier) instruction or equivalent CP15 instruction. - __isb⚠
Experimental Generates an ISB (instruction synchronization barrier) instruction or equivalent CP15 instruction. - __nop⚠
Experimental Generates an unspecified no-op instruction. - __sev⚠
Experimental Generates a SEV (send a global event) hint instruction. - __sevl⚠
Experimental Generates a send a local event hint instruction. - __
tcancel ⚠Experimental tme
Cancels the current transaction and discards all state modifications that were performed transactionally. - __
tcommit ⚠Experimental tme
Commits the current transaction. For a nested transaction, the only effect is that the transactional nesting depth is decreased. For an outer transaction, the state modifications performed transactionally are committed to the architectural state. - __
tstart ⚠Experimental tme
Starts a new transaction. When the transaction starts successfully the return value is 0. If the transaction fails, all state modifications are discarded and a cause of the failure is encoded in the return value. - __ttest⚠
Experimental tme
Tests if executing inside a transaction. If no transaction is currently executing, the return value is 0. Otherwise, this intrinsic returns the depth of the transaction. - __wfe⚠
Experimental Generates a WFE (wait for event) hint instruction, or nothing. - __wfi⚠
Experimental Generates a WFI (wait for interrupt) hint instruction, or nothing. - __yield⚠
Experimental Generates a YIELD hint instruction. - _prefetch⚠
Experimental Fetch the cache line that contains addressp
