| Subject: [PATCH] m4/stack-direction: RISC-V stack grows downward |
| |
| While commit 671b2528b55c57eda1a8fe5872ff1ef61014235f ("Improve |
| support for Linux/RISC-V") adds some support for the RISC-V |
| architecture, it doesn't update m4/stack-direction.m4 to properly |
| support cross-compiling libsigsegv for a RISC-V architecture. |
| |
| According to |
| https://riscv.org/wp-content/uploads/2015/01/riscv-calling.pdf: "In |
| the standard RISC-V calling convention, the stack grows downward", so |
| let's update m4/stack-direction.m4 accordingly. |
