The major idea + is to use shell scripts to generate everything. + * generic.em replaces ldtemplate. + * Other *.em files replace various *.c files. + A *.em file is a shell script that generates the corresponding + ld__*.c file that implements an emulation. This is usually + a straight 'cat' of a here-document, possibly with substitutions. + * Script files (*.sc) are places by *.sc-sh scripts. + Again, these are simple shell scripts that 'cat' + here-documents, usually with some substitutions. + The output a *.sc-sh is a script file. + * Each emulation is defined by a short shell script with + extension *.sh that specifies the emulation-specific + parameters (such as the name of the *.sh-sc and *.em + files to use). + * genscript.sh is the master shell script used to generate + an emulation. It is passed various argument, including + the name a the emulation-speciic *.sh file that it + "sources" to set variables to emulation-specifc parameters. + * config/mt-foo: Changed EMUL=GLDFOO_EMULATION_NAME + to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.) + * config/mh-foo: Rename LDEMULATION names as appropriate + (usually 'gldfoo' -> plain 'foo'). + * ldwrite.c: Fixed a typo in a comment. + * Makefile.in: Major changes. Removed some the sed + magic to converts scripts, since that is now handled + by genscripts.sh and the *.sc-sh scipt generators. + * config.h: Remove a bunch of macros defining emulations + and targets. This becomes one less file to edit when + adding emulations or targets. + * ldemul.h (struct ld_emulation_xfer_struct): Add + emulation_name and target_name fields. + * ldemul.c, ldemul.h: Define some default functions used + by most emulations (and remove from the *.em scripts). + * ldemul.c (ldemul_choose_target): Search the new + ld_emulations array using a loop (instead of a hardwired + nested if statement). + Define the ld_emulation from the automatically-geenrated + ldemul-list.h. This means you no longer have to edit ldemul.c + to add a new emulation. + * ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by + their expansions, since the former no longer exist. + * PORTING: A very rough first draft of a porting guide. + + * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment + to be terminated by a new-line (instead of requiring a semicolon). + +Mon Feb 10 16:21:02 1992 Steve Chamberlain (sac at rtl.cygnus.com) + + * ldexp.c, ldlang.c: added new idea "abs_output_section", removes + tests for NULL pointers all over the place. + * ldlang.c (lang_process): remember to relocate global symbols + *after* relaxing has done it stuff. + +Thu Feb 6 11:40:15 1992 Steve Chamberlain (sac at rtl.cygnus.com) + + * config/mt-coff-h8300: use EMUL like everything else + * ldlang.c: (print_padding_statement): print the right address. + * Makefile.in, config.h, ldemul.c: renamed h8300hds to h8300hms + + Tue Feb 4 15:28:01 1992 Steve Chamberlain (sac at rtl.cygnus.com) * ldlex.l: Put pack -noinhibit-exec and -sort-common |
