chez-scheme @10.0.0: error: use of unknown builtin '__builtin_add_overflow'

Priority: | Normal | Milestone: | |
Component: | ports | Version: | 2.9.3 |
Keywords: | yosemite, mavericks, mountainlion, lion, haspatch | Cc: | |
Port: | chez-scheme |
Description
There are no logs anymore, but I open the issue since I need this port for idris2
.
It builds and works on my 10.6 ppc, so should be fixable on x86 for sure.

In #60698 we worked around the problem by blacklisting {clang < 800}
. It would be better if chez-scheme would only use __builtin_add_overflow
if the compiler supports it. At present, they use it if USE_OVERFLOW_INTRINSICS
is defined, and they define it for gcc 5 or greater or any version of clang, which is clearly wrong. I filed a bug report with them here: https://github.com/cisco/ChezScheme/issues/845

Summary: | chez-scheme fails on 10.10 and earlier → chez-scheme @10.0.0: error: use of unknown builtin '__builtin_add_overflow' |
The error on Snow Leopard is different; see #70280.
