From 0537c71aa7ef88c4ffe754cf7af81e346273b079 Mon Sep 17 00:00:00 2001 From: Georg-Johann Lay Date: Tue, 23 May 2023 14:54:12 +0200 Subject: [PATCH] target/104327: Allow more inlining between different optimization levels. avr-common.cc introduces the following options that are set depending on optimization level: -mgas-isr-prologues, -mmain-is-OS-task and -fsplit-wide-types-early. The inliner thinks that different options disallow cross-optimization inlining, so provide can_inline_p. gcc/ PR target/104327 * config/avr/avr.cc (avr_can_inline_p): New static function. (TARGET_CAN_INLINE_P): Define to that function. --- gcc/config/avr/avr.cc | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/gcc/config/avr/avr.cc b/gcc/config/avr/avr.cc index e52f1d81db77..52aa5c26e1e6 100644 --- a/gcc/config/avr/avr.cc +++ b/gcc/config/avr/avr.cc @@ -1019,6 +1019,19 @@ avr_no_gccisr_function_p (tree func) return avr_lookup_function_attribute1 (func, "no_gccisr"); } + +/* Implement `TARGET_CAN_INLINE_P'. */ +/* Some options like -mgas_isr_prologues depend on optimization level, + and the inliner might think that due to different options, inlining + is not permitted; see PR104327. */ + +static bool +avr_can_inline_p (tree /* caller */, tree /* callee */) +{ + // No restrictions whatsoever. + return true; +} + /* Implement `TARGET_SET_CURRENT_FUNCTION'. */ /* Sanity cheching for above function attributes. */ @@ -14768,6 +14781,9 @@ avr_float_lib_compare_returns_bool (machine_mode mode, enum rtx_code) #undef TARGET_MD_ASM_ADJUST #define TARGET_MD_ASM_ADJUST avr_md_asm_adjust +#undef TARGET_CAN_INLINE_P +#define TARGET_CAN_INLINE_P avr_can_inline_p + struct gcc_target targetm = TARGET_INITIALIZER; -- 2.47.3
