Package: ghc Version: 9.10.3-1 Severity: normal X-Debbugs-Cc: [email protected]
Dear Maintainer, On Loong64, NCG is currently not supported in 9.10, while Llvm backend incompatible with tables-next-to-code, which will generate PLT for non- function symbols. Only lld can correctly link it. Specifics can be seen: https://gitlab.haskell.org/ghc/ghc/-/issues/25531 And the 0005-* patch is also required for C files. -- System Information: Debian Release: forky/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: loong64 (loongarch64) Kernel: Linux 6.6.34-9.2.loongarch64 (SMP w/32 CPU threads) Kernel taint flags: TAINT_UNSIGNED_MODULE Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: unable to detect Versions of packages ghc depends on: ii dpkg 1.22.21 ii gcc 4:15.2.0-4 ii libbsd-dev 0.12.2-2 ii libc6 2.41-12 ii libc6-dev 2.41-12 ii libffi-dev 3.5.2-2 ii libffi8 3.5.2-2 ii libgmp-dev 2:6.3.0+dfsg-5 ii libgmp10 2:6.3.0+dfsg-5 ii libncurses-dev 6.5+20250216-2 ii libnuma-dev 2.0.19-1 ii libnuma1 2.0.19-1 ii libtinfo6 6.5+20250216-2 ii llvm-18 1:18.1.8-18+b2 Versions of packages ghc recommends: ii libstdc++-14-dev 14.3.0-8 Versions of packages ghc suggests: pn ghc-doc <none> pn ghc-prof <none> ii perl 5.40.1-6 -- no debconf information
