Richard E.'s generic solution has never been implemented so let's do as other RISC back-ends did. gcc/ PR target/107248 * config/sparc/sparc.cc (sparc_expand_prologue): Emit a frame blockage for leaf functions. (sparc_flat_expand_prologue): Emit frame instead of full blockage. (sparc_expand_epilogue): Emit a frame blockage for leaf functions. (sparc_flat_expand_epilogue): Emit frame instead of full blockage.
