2011-06-24runtime: don't use twice the memory with grsec-like kernelsGustavo Niemeyer
grsec needs the FIXED flag to be provided to mmap, which works now. That said, when the allocation fails to be made in the specific address, we're still given back a writable page. This change will unmap that page to avoid using twice the amount of memory needed. It'd also be pretty easy to avoid the extra system calls once we detected that the flag is needed, but I'm not sure if that edge case is worth the effort.

This program used to use R9 and R10. Now it fails to compile (out of registers). I used to know a simpler test but can't remember it.

2011-06-22ld: don't attempt to build dynamic sections unnecessarilyGustavo Niemeyer
This prevents ld from generating zeroed symtab entries for sections that aren't going to be generated because dynamic linkage has been disabled (-d was used or no dynamic libs were seen). Even though they were not explicitly added by doelf, the section creation process was making them reachable again. The windows head is being disconsidered for this because apparently it's not taking into account debug['d']. This makes elflint 0.1% happier.

2011-06-21godefs: remove test from buildRuss Cox
The test is only defined on darwin/amd64, and it fails with recent versions of Xcode, which do not support -gstabs+ debugging output. At some point godefs will have to be replaced, perhaps merged with cgo. Godefs is not needed during builds anyway (its output files are checked into the repository in src/pkg/runtime), so its failure on the newer Xcode is a distraction from an otherwise usable build. Disable the test. Fixes #1985. R=golang-dev, gri, robert.hencke, r CC=golang-dev https://golang.org/cl/4638053

2011-06-218l: more fixes for Plan 9Lucio De Re
Once these changes are effected, it is possible to construct "8l" native on a (386?) Plan 9 system, albeit with assistance from modules such as mkfiles that are not (yet) included in any public patches. 8l/asm.c: . Corrected some format qualifiers. 8l/list.c: . Cast a print() argument to (int) to match the given format. It may be possible to change the format (%R), but I have not looked into it. 8l/obj.c: . Removed some unused code. 8l/span.c: . Removed unnecessary incrementation on "bp". . Corrected some format qualifiers. ld/data.c: . Corrected some format qualifiers. . Cast print argument to (int): used as field size. . Use braces to suppress warning about empty if() statements. ld/dwarf.c: . Trivial spelling mistake in comment. ld/ldelf.c: . Added USED() statements to silence warnings. . Dropped redundant address (&) operators. . corrected some format qualifiers. . Cast to (int) for switch selection variable. ld/macho.c: . Added USED() statements to silence warnings. ld/ldpe.c: . Added USED() statements to silence warnings. . More careful use of "sect" variable. . Corrected some format qualifiers. . Removed redundant assignments. . Minor fix dropped as it was submitted separately. ld/pe.c: . Dropped <time.h> which is now in <u.h>. . Dropped redundant address (&) operators. . Added a missing variable initialisation. ld/symtab.c: . Added USED() statements to silence warnings. . Removed redundant incrementation. . Corrected some format qualifiers. All the above have been tested against a (very) recent release and do not seem to trigger any regressions. All review suggestions have been incorporated.

2011-06-21fmt: catch panics from calls to String etc.Rob Pike
This change causes Print et al. to catch panics generated by calls to String, GoString, and Format. The panic is formatted into the output stream as an error, but the program continues. As a special case, if the argument was a nil pointer, the result is just "<nil>", because that's almost certainly enough information and handles the very common case of String methods that don't guard against nil. Scan does not want this change. Input must work; output can be for debugging and it's nice to get output even when you make a mistake.
