commit 6ebb2c46d5eae7bae8d827fdc68d3ed58b16e95a Author: Alex Crichton alex@alexcrichton.com Date: Mon Oct 1 22:50:08 2018 -0700
Remove the `link_rust.sh.in` script
This is no longer necessary with upstream rust-lang/rust changes as well as some local tweaks. Namely:
* The `-fsanitize=address`-style options are now passed via `-C link-args` through `RUSTFLAGS`. This obviates the need for the shell script. * The `-C default-linker-libraries`, disabling `-nodefaultlibs`, is passed through `RUSTFLAGS`, which is necessary to ensure that `-fsanitize=address` links correctly. * The `-C linker` option is passed to ensure we're using the same C compiler as normal C code, although it has a bit of hackery to only get the `gcc` out of `gcc -std=c99` --- configure.ac | 9 ++++----- link_rust.sh.in | 10 ---------- src/test/include.am | 3 +-- 3 files changed, 5 insertions(+), 17 deletions(-)
