13 # The first argument passed to this file is the canonical host specification,
14 # CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
15 # or
16 # CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
17 # The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld
18 # should be set by the caller.
19 #
20 # The set of defined variables is at the end of this script.
22 # Known limitations:
23 # - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
24 # than 256 bytes, otherwise the compiler driver will dump core. The only
25 # known workaround is to choose shorter directory names for the build
26 # directory and/or the installation directory.
28 # All known linkers require a `.a' archive for static linking (except MSVC,
29 # which needs '.lib').
