release 2020Q3
The biggest change in this release is the addition of 4 new documents:
- Exception Handling ABI for the Arm Architecture
- C Library for the Arm Architecture
- Addenda to, and Errata in, the ABI for the ARM Architecture
- ELF for the Arm 64-bit Architecture
Additionally, we've specified ABI handling for 8.7-A's new FPCR bits in the aapcs64 and we added a missing table entry for Tag_DSP_extension in the addenda32 document (as compared to the latest version up on developer.arm.com).
