2015-01-15libgo: Bump version number in libgo configure script.Ian Lance Taylor1-1/+1
From-SVN: r219629
2015-01-15libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.Ian Lance Taylor1-1/+1
This upgrades all of libgo other than the runtime package to the Go 1.4 release. In Go 1.4 much of the runtime was rewritten into Go. Merging that code will take more time and will not change the API, so I'm putting it off for now. There are a few runtime changes anyhow, to accomodate other packages that rely on minor modifications to the runtime support. The compiler changes slightly to add a one-bit flag to each type descriptor kind that is stored directly in an interface, which for gccgo is currently only pointer types. Another one-bit flag (gcprog) is reserved because it is used by the gc compiler, but gccgo does not currently use it. There is another error check in the compiler since I ran across it during testing. gotools/: * Makefile.am (go_cmd_go_files): Sort entries. Add generate.go. * Makefile.in: Rebuild. From-SVN: r219627

2014-11-14runtime: set library name based on compiler nameIan Lance Taylor1-0/+8
Different compilers may have different release cadences or ABI incompatibilities, so it does not make sense to use the same library name for runtime libraries intended for different compilers. This CL causes a libgo built by llgo to receive the name libgo-llgo. Likewise, libgobegin is named libgobegin-llgo. From-SVN: r217583

From Dominik Vogt. From-SVN: r216355
2014-09-29libgo/configure: Use -Qunused-arguments for asm tests if supported.Ian Lance Taylor1-0/+24
This supports clang, which by default issues warnings about unused command line arguments, a habit that interacts poorly with configure scripts. From-SVN: r215699

From-SVN: r212840
2014-05-29runtime: add the --without-libatomic configure optionIan Lance Taylor1-0/+15
This adds the --without-libatomic configure option, which is useful for building libgo with a non-gcc compiler. It disables libgo's dependency on libatomic. This is useful for platforms where it is known that the libatomic runtime functions are not required, or where the compiler automatically provides an implementation of them. From-SVN: r211065

I am reliably informed that the architecture name and letter for the plan9/inferno compilers for 64-bit ARM systems will be "arm64" and "7" respectively, so let's get that bit in nice and early. From Michael Hudson-Doyle. https://codereview.appspot.com/34830045/ From-SVN: r206374

2013-06-18compiler, runtime: Use function descriptors.Ian Lance Taylor1-1/+1
This changes the representation of a Go value of function type from being a pointer to function code (like a C function pointer) to being a pointer to a struct. The first field of the struct points to the function code. The remaining fields, if any, are the addresses of variables referenced in enclosing functions. For each call to a function, the address of the function descriptor is passed as the last argument. This lets us avoid generating trampolines, and removes the use of writable/executable sections of the heap. From-SVN: r200181
