This is invoked by the autoconf-generated 24# configure script. Putting it in a separate shell file lets us skip 25# running autoconf when modifying host-specific information. 26 27# This file bears an obvious resemblance to gcc/config.gcc. The cases 28# should be kept similar, to ease moving library-specific settings 29# from config.gcc to this file. That is also why tmake_file is 30# left as tmake_file, rather than hmake_file, even though this library 31# switches on ${host}. 32 33# This file switches on the shell variable ${host}, and also uses the 34# following shell variables: 35# 36# with_* Various variables as set by configure. 37 38# This file sets the following shell variables for use by the 39# autoconf-generated configure script: 40# 41# asm_hidden_op The assembler pseudo-op to use for hide 42# lists for object files implemented in 43# assembly (with -fvisibility=hidden for C). 44# The default is ".hidden". 45# cpu_type The name of the cpu, if different from the first 46# chunk of the canonical host name. 47# extra_parts List of extra object files that should be compiled 48# for this target machine. This may be overridden 49# by setting EXTRA_PARTS in a tmake_file fragment. 50# If either is set, EXTRA_PARTS and 51# EXTRA_MULTILIB_PARTS inherited from the GCC 52# subdirectory will be ignored. 53# tmake_file A list of machine-description-specific 54# makefile-fragments, if different from 55# "$cpu_type/t-$cpu_type". 56 57asm_hidden_op=.hidden 58extra_parts= 59tmake_file= 60 61# Set default cpu_type so it can be updated in each machine entry. 62cpu_type=`echo ${host} | sed 's/-.*$//'` 63case ${host} in 64m32c*-*-*) 65 cpu_type=m32c 66 ;; 67alpha*-*-*) 68 cpu_type=alpha 69 ;; 70am33_2.0-*-linux*) 71 cpu_type=mn10300 72 ;; 73arm*-*-*) 74 cpu_type=arm 75 ;; 76avr-*-*) 77 cpu_type=avr 78 ;; 79bfin*-*) 80 cpu_type=bfin 81 ;; 82fido-*-*) 83 cpu_type=m68k 84 ;; 85frv*) cpu_type=frv 86 ;; 87moxie*) cpu_type=moxie 88 ;; 89i[34567]86-*-*) 90 cpu_type=i386 91 ;; 92x86_64-*-*) 93 cpu_type=i386 94 ;; 95ia64-*-*) 96 ;; 97hppa*-*-*) 98 cpu_type=pa 99 ;; 100lm32*-*-*) 101 cpu_type=lm32 102 ;; 103m32r*-*-*) 104 cpu_type=m32r 105 ;; 106m68k-*-*) 107 ;; 108mep*-*-*) 109 ;; 110mips*-*-*) 111 cpu_type=mips 112 ;; 113powerpc*-*-*) 114 cpu_type=rs6000 115 ;; 116rs6000*-*-*) 117 ;; 118score*-*-*) 119 cpu_type=score 120 ;; 121sparc64*-*-*) 122 cpu_type=sparc 123 ;; 124sparc*-*-*) 125 cpu_type=sparc 126 ;; 127spu*-*-*) 128 cpu_type=spu 129 ;; 130s390*-*-*) 131 cpu_type=s390 132 ;; 133# Note the 'l'; we need to be able to match e.g. "shle" or "shl". 134sh[123456789lbe]*-*-*) 135 cpu_type=sh 136 ;; 137esac 138 139# Common parts for widely ported systems. 140case ${host} in 141*-*-darwin*) 142 asm_hidden_op=.private_extern 143 tmake_file="t-darwin ${cpu_type}/t-darwin t-slibgcc-darwin" 144 ;; 145*-*-freebsd[12] | *-*-freebsd[12].* | *-*-freebsd*aout*) 146 # This is the place-holder for the generic a.out configuration 147 # of FreeBSD.
