# A .sc script file is needed for each emulation mode.
# sed is used to transform this script into two variant forms:
# A .scr script is for linking without relocation (-r flag).
# A .scu script is like .scr, but *do* create constructors.
# A .scn script is for linking with -N flag (mix text and data on same page).
# A .scN script is for linking with -N flag (mix text and data on same page).
# The diference is that segments should (need) not be page aligned.

# A sed pattern to translate .sc to .scu:
SED_MAKE_RELOC_WITH_CONSTRUCTORS=\
  -e "/If relocating/,/End if relocating/d" \
  -e "/=/s/[_a-zA-Z.]* *= .*//g" \
  -e '/>/s/} *> *[a-zA-Z]*/}/' \
  -e "/text/s/[.]text .*:/.text :/" \
  -e "/data/s/[.]data .*:/.data :/"
# A sed pattern to translate .scu to .scr:
SED_REMOVE_CONSTRUCTORS= -e /CONSTRUCTORS/d

.sc.scu:
	sed $(SED_MAKE_RELOC_WITH_CONSTRUCTORS) $< >$*.scu
.scu.scr:
	sed $(SED_REMOVE_CONSTRUCTORS) < $< >$*.scr

# Each builtin script file is included as a C string literal.
# These are generated by the mkscript filter.
.sc.x:
	if [ "x"$(LIB_PATH) = "x" ]; then ./mkscript < $< >$*.x ; \
	else \
	  (sed <$< -e '/SEARCH_DIR(.*)/d' ; \
	  echo $(LIB_PATH) | tr ':' ' ' | sed -e 's/\([^ ][^ ]*\)/SEARCH_DIR(\1);/g';) | ./mkscript >$*.x;\
	fi

# The .xn script is used if the -n flag is given (write-protect text)..
# Sunos starts the text segment for demand-paged binaries at 0x2020
# and other binaries at 0x2000, since the exec header is paged in
# with the text.  Some other Unix variants do the same.
# For -n and -N flags the offset of the exec header must be removed.
# This sed script does this if the master script contains
# a line of the form ".text 0xAAAA BLOCK(0xBBBB):" - the
# output will contain ".text 0xBBBB:".  (For Sunos AAAA=2020 and BBBB=2000.)
.x.xn:
	sed -e '/text/s/\.text .* BLOCK(\([^)]*\)):/.text \1:/' < $< >$*.xn

# The .xN script is used if the -N flag is given (don't write-protect text).
# This is like -n, except that the data segment need not be page-aligned.
# So get rid of commands for page-alignment:  We assume these use ALIGN
# with a hex constant that end with 00, since any normal page size is be
# at least divisible by 256.  We use the 00 to avoid matching
# anything that tries to align of (say) 8-byte boundaries.
.xn.xN:
	sed -e '/ALIGN/s/ALIGN( *0x[0-9a-fA-F]*00 *)/./' < $< >$*.xN

# The xu and xr scripts don't search libraries, so LIB_PATH doesn't matter.
