Anyway, I would found it a nice feature, at startup or when running the version command, but both aren't a must.
I think it would be a really useful extension to the version command. Looking forwad to seeing your patch.
Maybe if someone could feed me with what to use for the version. E.g. my gcc here defines __VERSION__ as "4.5.2" but when I'm looking at u-boot/lib/asm-offsets.s I see
.ident "GCC: (Gentoo 4.5.2 p1.0, pie-0.4.5) 4.5.2"
So I would like to display that which would be in line with the comment section of generated binaries.
But when I use "gcc -E -dM empty.c" to print all predefined macros, I don't see the text found in .ident. Not even something else which includes "Gentoo".
I believe the output of "$(CC) --version" should contain the same data as your .ident string. You could echo it into a file like: diff --git a/Makefile b/Makefile index 0685ef9..e070d40 100644 --- a/Makefile +++ b/Makefile @@ -416,6 +416,8 @@ $(U_BOOT_ONENAND): $(ONENAND_IPL) $(obj)u-boot.bin $(VERSION_FILE): @( printf '#define U_BOOT_VERSION "U-Boot %s%s"\n' "$(U_BOOT_VERSION)" \ '$(shell $(TOPDIR)/tools/setlocalversion $(TOPDIR))' ) > $@.tmp + @( printf '#define CC_VERSION_STRING "%s"\n' \ + '$(shell $(CC) --version | head -1)' ) >> $@.tmp @cmp -s $@ $@.tmp && rm -f $@.tmp || mv -f $@.tmp $@
