From 3923460dda205721d9bee2714a7f0dd403082a90 Mon Sep 17 00:00:00 2001 From: Cherry Zhang Date: Sat, 3 Oct 2020 16:18:43 -0400 Subject: runtime/cgo: only build xx_cgo_panicmem on iOS On iOS, when running under lldb, we install xx_cgo_panicmem as EXC_BAD_ACCESS handler so we can get a proper Go panic for SIGSEGV. Only build it on iOS. Updates #38485.
