[M3devel] cm3 on snow leopard?

[Jay K]

Please try my updated Darwin.common.

IsX86 = equal(TARGET, "I386_DARWIN") or equal(TARGET, "AMD64_DARWIN")

proc configure_assembler() is
  if defined("SYSTEM_ASM")
    return
  end
  SYSTEM_ASM = "/usr/libexec/gcc/darwin/" & DarwinArch & "/as"
  if not FileExists(SYSTEM_ASM)
    if IsX86
      configure_c_compiler ()
      SYSTEM_ASM = SYSTEM_CC_ASM & " -c -x assembler"
    else
      SYSTEM_ASM = "as"
    end
  end
  %SYSTEM_ASM = SYSTEM_CC_ASM & " -v -c -x assembler"
end

proc configure_c_compiler() is

  if defined("SYSTEM_CC")
    return
  end

  %
  % older compiler doesn't like -m32 or -arch
  %
  % gcc -c -m32 -x c /dev/null
  % cc1: error: invalid option ‘m32’
  %
  % fPIC is not usually needed here.
  % It is the default for Apple gcc and left
  % here in case user is using a self-built FSF gcc.
  %

  SYSTEM_CC = "gcc -gstabs+ -fPIC"
  SYSTEM_CC_ASM = "gcc -fPIC"
  local m = " -m" & {"32BITS":"32","64BITS":"64"}{WORD_SIZE}
  local arch = " -arch " & DarwinArch
  if not equal(try_exec("@" & SYSTEM_CC & m & " -c -x c /dev/null -o /dev/null 2>&1 | fgrep \"cc1: error: invalid option \\\`32'\" >/dev/null"), 0)
    SYSTEM_CC = SYSTEM_CC & m
    SYSTEM_CC_ASM = SYSTEM_CC_ASM & m
  end
  if not equal(try_exec("@" & SYSTEM_CC & arch & " -c -x c /dev/null -o /dev/null 2>&1 | fgrep \"cc1: error: unrecognized command line option \\\\\"-arch\\\\\"\" >/dev/null"), 0)
    SYSTEM_CC = SYSTEM_CC & arch
    SYSTEM_CC_ASM = SYSTEM_CC_ASM & arch
  end
  %write("SYSTEM_CC is " & SYSTEM_CC)
end

I'm more sympathetic to using the already installed C compiler
to drive the assembler, than to build the current gcc driver.


You can see on Darwin we already probe around fairly aggressively
for a C compiler that can be told the target:

Darwin.common:


proc configure_c_compiler() is

  if defined("SYSTEM_CC")
    return
  end

  %
  % older compiler doesn't like -m32 or -arch
  %
  % gcc -c -m32 -x c /dev/null
  % cc1: error: invalid option ‘m32’
  %
  % fPIC is not usually needed here.
  % It is the default for Apple gcc and left
  % here in case user is using a self-built FSF gcc.
  %

  SYSTEM_CC = "gcc -gstabs+ -fPIC"
  local m = " -m" & {"32BITS":"32","64BITS":"64"}{WORD_SIZE}
  local arch = " -arch " & DarwinArch
  if not equal(try_exec("@" & SYSTEM_CC & m & " -c -x c /dev/null -o /dev/null 2>&1 | fgrep \"cc1: error: invalid option \\\`32'\" >/dev/null"), 0)
    SYSTEM_CC = SYSTEM_CC & m
  end
  if not equal(try_exec("@" & SYSTEM_CC & arch & " -c -x c /dev/null -o /dev/null 2>&1 | fgrep \"cc1: error: unrecognized command line option \\\\\"-arch\\\\\"\" >/dev/null"), 0)
    SYSTEM_CC = SYSTEM_CC & arch
  end
  %write("SYSTEM_CC is " & SYSTEM_CC)
end


Most likely if we merely set SYSTEM_ASM = SYSTEM_CC & "-x assembler"
it'll work well.
Maybe only in this else case:


proc configure_assembler() is
  if defined("SYSTEM_ASM")
    return
  end
  SYSTEM_ASM = "/usr/libexec/gcc/darwin/" & DarwinArch & "/as"
  if not FileExists(SYSTEM_ASM)
      SYSTEM_ASM = "as" <<== here
  end
end


All this is addressed by autoconf and/or a C-generating backend.....

I'm rudely (but helpfully) ignoring your details and giving some of mine.

I though what is supposed to happen, specifically on Darwin, is the assembly code is supposed to indicate an architecture.

jbook2:m3core jay$ CM3_TARGET=I386_DARWIN M3CONFIG=/cm3/bin/config/I386_DARWIN cm3 -keep
^C

jbook2:m3core jay$ CM3_TARGET=AMD64_DARWIN M3CONFIG=/cm3/bin/config/AMD64_DARWIN cm3 -keep
^C

head */RTHooks.ms

but no.

But then this:

jbook2:m3core jay$ CM3_TARGET=AMD64_DARWIN M3CONFIG=/cm3/bin/config/AMD64_DARWIN cm3 -keep -commands
--- building in AMD64_DARWIN ---

..
/usr/libexec/gcc/darwin/x86_64/as RTAllocator.ms -o RTAllocator.mo

CM3_TARGET=I386_DARWIN M3CONFIG=/cm3/bin/config/I386_DARWIN cm3 -keep -commands

...
/usr/libexec/gcc/darwin/i386/as Ctypes.is -o Ctypes.io

i386 vs. x86_64.

Darwin.common:
proc configure_assembler() is
  if defined("SYSTEM_ASM")
    return
  end
  SYSTEM_ASM = "/usr/libexec/gcc/darwin/" & DarwinArch & "/as"
  if not FileExists(SYSTEM_ASM)
      SYSTEM_ASM = "as"
  end
end


jbook2:m3core jay$ grep DarwinArch /dev2/cm3/m3-sys/cminstall/src/config-no-install/*
/dev2/cm3/m3-sys/cminstall/src/config-no-install/AMD64_DARWIN:DarwinArch = "x86_64"
/dev2/cm3/m3-sys/cminstall/src/config-no-install/ARM_DARWIN:DarwinArch = "armv6" % ?
/dev2/cm3/m3-sys/cminstall/src/config-no-install/Darwin.common:  SYSTEM_ASM = "/usr/libexec/gcc/darwin/" & DarwinArch & "/as"
/dev2/cm3/m3-sys/cminstall/src/config-no-install/Darwin.common:  local arch = " -arch " & DarwinArch
/dev2/cm3/m3-sys/cminstall/src/config-no-install/Darwin.common:      arch = " -arch_only " & DarwinArch & " "
/dev2/cm3/m3-sys/cminstall/src/config-no-install/I386_DARWIN:DarwinArch = "i386"
/dev2/cm3/m3-sys/cminstall/src/config-no-install/PPC64_DARWIN:DarwinArch = "ppc64"
/dev2/cm3/m3-sys/cminstall/src/config-no-install/PPC_DARWIN:DarwinArch = "ppc"

?
cm3 -commands?

find /usr/lib | grep /as$
find /usr/libexec | grep /as$


Maybe the path changed? Has a version? or is there is only i686-apple-darwin9, powerpc-apple-darwin9?

I should look into getting the architecture into the assembly code though and just running "as", esp. on newer hosts.

I admit I'm still using Leopard.
