# 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" \

# 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.
