2363	"Inconsistencies concerning ""bootstrapping"" in GCC instructions"	chris@…	bdubbs@…	"In the Chapter 6 GCC instructions, it says...

For x86 machines, the bootstrap build performed in Section 5.10, “GCC-4.3.3 - Pass 2” built GCC with the -fomit-frame-pointer compiler flag. Non-bootstrap builds omit this flag by default, so apply the following sed to use it in order to ensure consistent compiler builds:

This is incorrect, as GCC Pass 2 is not built bootstrapped, so the first sentence of that paragraph should be altered to reflect that. Further, as it is, GCC is never bootstrapped at any point in the book, so it is never explained what ""bootstrapping"" means for GCC. I believe that the explanation of what ""bootstrapping"" means for GCC should be added to the explanation for the --disable-bootstrap switch in GCC Pass 2. Also, the text about the --disable-bootstrap switch, ""Bootstrapping the compiler is now the default for GCC."" should be amended to specify ""for native builds."" I've attached a patch with these suggested changes, as well as a little text shuffling between Chapters 5 and 6, with the description of ""bootstrapping"" copied from a previous LFS version.

Also, I didn't include this in the patch, but would I be right in assuming that the case statement that adds -fomit-frame-pointer only for x86 in Chapter 6 should also be used in Pass 2?"	task	closed	normal	6.5	Book	SVN	normal	fixed
