[build] Fix DEBUG builds for filenames with hyphens

2009-10-15T18:07:20+00:00

Debug builds for filenames with hyphens such as: $ make bin/via-rhine.dsk DEBUG=via-rhine fail with: [BUILD] bin/via-rhine.dbg1.o : error: missing whitespace after the macro name make: *** [bin/via-rhine.dbg1.o] Error 1 This is because "-" is not a legal character in C identifiers, and gcc rejects "-Ddebug_via-rhine=1" as an argument.

[doc] Expand scope of doxygen-generated documentation

[build] Add -fno-dwarf2-cfi-asm to CFLAGS if supported by the gcc in use

2009-05-27T01:30:46+00:00

gcc 4.4 defaults to using .cfi assembler directives for debugging information, which causes unneeded .eh_frame sections to be generated. These sections are already stripped out by our linker script, so don't affect the final build, but do distort the output of "size" when run on individual .o files; the .eh_frame size is included within the size reported for .text. This makes it difficult to accurately judge the effects of source code changes upon object code size. Fix by adding -fno-dwarf2-cfi-asm to CFLAGS if we detect that this option is supported by the gcc that we are compiling with. Tested-by: Daniel Verkamp

[legal] Add licence.pl and %.licence make target

2009-05-18T07:29:24+00:00

It is now possible to run e.g. make bin/rtl8139.dsk.licence in order to see a licensing assessment for any given gPXE build. The assessment will either produce a single overall licence for the build (based on combining all the licences used within the source files for that build), or will exit with an error stating why a licence assessment is not possible (for example, if there are files involved that do not yet contain an explicit FILE_LICENCE() declaration).

[build] Automatically sort the list of constituent object sizes

2009-04-18T15:20:03+00:00

[build] Provide mechanism for listing constituent object sizes

2009-04-18T14:56:29+00:00

You can now type e.g. make bin/rtl8139.rom.sizes in order to see the (uncompressed) sizes of all of the object files linked in to bin/rtl8139.rom. This should make it easier to identify relevant code bloat.

[build] Kill off the multiple-object-per-source-file mechanism

2009-04-17T12:43:35+00:00

Now that there are no remaining multiple-object source files, kill off the mechanism in order to simplify the Makefile.

[build] Provide mechanism for listing per-target source files

2009-04-17T11:38:44+00:00

You can now type e.g. make bin/rtl8139.rom.deps to see a list of the source files included in the build of bin/rtl8139.rom. This is intended to assist with copyright vetting. Other new debugging targets include make bin/rtl8139.rom.objs to see a list of object files linked in to bin/rtl8139.rom, and make bin/rtl8139.rom.nodeps to see a list of the source files that are *not* required for the build of bin/rtl8139.rom.

[build] Pad .rom, .dsk, and .hd images to 512-byte boundaries

2009-04-16T02:15:08+00:00

QEMU will silently round down a disk or ROM image file to the nearest 512 bytes. Fix by always padding .rom, .dsk and .hd images to the nearest 512-byte boundary. Originally-fixed-by: Stefan Hajnoczi

[build] Don't assume the existence of "seq"

2009-03-31T10:06:35+00:00

The "seq" command is GNU-specific; a BSD userland will not have it. Use POSIX-conforming "awk" instead. Reported-by: Joshua Oreman Suggested-by: Stefan Hajnoczi
