Russ Cox	3f61184e1b	gc, ld: detect stale or incompatible object files ... The object files begin with a header that is $GOARCH on a line by itself. This CL changes that header to go object $GOOS $GOARCH release.2011-01-01 4567+ where the final two fields are the most recent release tag and the current hg version number. All objects imported into a Go compilation or linked into an executable must have the same header line, and that header line must match the compiler and linker versions. The effect of this will be that if you update and run all.bash and then try to link in objects compiled with an earlier version of the compiler (or invoke the wrong version of the compiler), you will get an error showing the different headers instead of perhaps silent incompatibility. Normal usage with all.bash should be unaffected, because all.bash deletes all the object files in $GOROOT/pkg/$GOOS_$GOARCH and cleans all intermediate object files before starting. This change is intended to diagnose stale objects arising when users maintaining alternate installation directories forget to rebuild some of their files after updating. It should help make the adoption of $GOPATH (CL 3780043) less error-prone. R=ken2, r CC=golang-dev https://golang.org/cl/4023063	2011-02-03 13:51:43 -05:00

Russ Cox	d9c989fa25	various: avoid %ld etc ... The Plan 9 tools assume that long is 32 bits. We converted all instances of long to int32 when importing the code but missed the print formats. Because int32 is always int on the compilers we use, it is never correct to use %lux, %ld, etc. Convert to %ux, %d, etc. (It matters because on 64-bit gcc, long is 64 bits, so we were printing 32-bit quantities with 64-bit formats.)

Kai Backman	99cc2fee81	This is really two changes in one but given interdependencies ... and expected review latency I needed to combine the CLs. 1. Made the 5* toolpath build using the go build system. Hooked the subdirectories to clean.bash but added a separate make5.bash for now. Minor massage to make the code more similar to the current structure of 6c/6a/6l. 2. Change all references from long to int32 in line with similar change for the other toolchains. The end result is that 5c, 5a and 5l can now be compiled and the executables start up properly. Haven't thrown any input at them yet.
