The `--disable-jemalloc` configure option has a failure mode where it will create a distribution that is not compatible with other compilers. For example the nightly for Linux will assume that it will link to jemalloc by default as an allocator for executable crates. If, however, a standard library is used which was built via `./configure --disable-jemalloc` then this will fail because the jemalloc crate wasn't built. While this seems somewhat reasonable as a niche situation, the same mechanism is used for disabling jemalloc for platforms that just don't support it. For example if the rumprun target is compiled then the sibiling Linux target *also* doesn't have jemalloc. This is currently a problem for our cross-build nightlies which build many targets. If rumprun is also built, it will disable jemalloc for all targets, which isn't desired. This commit moves the platform-specific disabling of jemalloc as hardcoded logic into the makefiles that is scoped per-platform. This way when configuring multiple targets **without the `--disable-jemalloc` option specified** all targets will get jemalloc as they should.

# Rust's standard distribution of crates and tools
|
|
#
|
|
# The crates outlined below are the standard distribution of libraries provided
|
|
# in a rust installation. These rules are meant to abstract over the
|
|
# dependencies (both native and rust) of crates and basically generate all the
|
|
# necessary makefile rules necessary to build everything.
|
|
#
|
|
# Here's an explanation of the variables below
|
|
#
|
|
# TARGET_CRATES
|
|
# This list of crates will be built for all targets, including
|
|
# cross-compiled targets
|
|
#
|
|
# HOST_CRATES
|
|
# This list of crates will be compiled for only host targets. Note that
|
|
# this set is explicitly *not* a subset of TARGET_CRATES, but rather it is
|
|
# a disjoint set. Nothing in the TARGET_CRATES set can depend on crates in
|
|
# the HOST_CRATES set, but the HOST_CRATES set can depend on target
|
|
# crates.
|
|
#
|
|
# TOOLS
|
|
# A list of all tools which will be built as part of the compilation
|
|
# process. It is currently assumed that most tools are built through
|
|
# src/driver/driver.rs with a particular configuration (there's a
|
|
# corresponding library providing the implementation)
|
|
#
|
|
# DEPS_<crate>
|
|
# These lists are the dependencies of the <crate> that is to be built.
|
|
# Rust dependencies are listed bare (i.e. std) and native
|
|
# dependencies have a "native:" prefix (i.e. native:hoedown). All deps
|
|
# will be built before the crate itself is built.
|
|
#
|
|
# TOOL_DEPS_<tool>/TOOL_SOURCE_<tool>
|
|
# Similar to the DEPS variable, this is the library crate dependencies
|
|
# list for tool as well as the source file for the specified tool
|
|
#
|
|
# You shouldn't need to modify much other than these variables. Crates are
|
|
# automatically generated for all stage/host/target combinations.
