W-M-R opened a new pull request, #15508:
URL: https://github.com/apache/nuttx/pull/15508
## Summary
When assembly code calls a C function, it needs to save the context. After
enabling KASAN, the inserted __asan_load8_noabort function uses the rsi
register, causing the value of rsi in the interrupt handler to be modified,
which results in an incorrect interrupt number.
## Impact
*Update this section, where applicable, on how change affects users,
build process, hardware, documentation, security, compatibility, etc.*
## Testing
*Update this section with details on how did you verify the change,
what Host was used for build (OS, CPU, compiler, ..), what Target was
used for verification (arch, board:config, ..), etc. Providing build
and runtime logs from before and after change is highly appreciated.*
