>From a7dd704507b2c2b139cb2dced91274da38aa948a Mon Sep 17 00:00:00 2001 From: Kushal Pal <[email protected]> Date: Mon, 25 May 2026 16:41:40 +0530 Subject: [PATCH] [Clang][Hexagon] Use flat library directory layout for Picolibc For the non-Picolibc Hexagon ELF toolchain, variant libraries are organized in a nested directory hierarchy: lib/<cpu>/G0/pic/ For Picolibc, switch to a flat parallel layout where the CPU version, G0, and pic qualifiers are encoded as a single hyphen-separated directory name: lib/<cpu>-G0-pic/ (PIC + G0) lib/<cpu>-G0/ (G0 only) lib/<cpu>/ (base) This applies to both the library search paths (-L flags, via getHexagonLibraryPaths) and the start-file directory (crt0 lookup, via getLibraryDir). The non-Picolibc toolchain is unaffected. The flat layout is easier to package (no deeply nested install trees), self-documenting, and closer to how other embedded toolchains expose multilib variants as parallel directories. Update hexagon-toolchain-picolibc.c to reflect the new paths, and add --sysroot tests that verify include paths, library search paths, and start-file selection for the base, G0, and G0-pic variants.
