28 # The first argument passed to this file is the canonical host specification,
29 # CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
30 # or
31 # CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
32 # The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld
33 # should be set by the caller.
34 #
35 # The set of defined variables is at the end of this script.
36
37 # Known limitations:
38 # - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
39 # than 256 bytes, otherwise the compiler driver will dump core. The only
40 # known workaround is to choose shorter directory names for the build
41 # directory and/or the installation directory.
42
43 # All known linkers require a `.a' archive for static linking (except M$VC,
44 # which needs '.lib').
