From 66cc0cb0f44f17049f61af6755043999c4fa5a24 Mon Sep 17 00:00:00 2001 From: Georg-Johann Lay Date: Tue, 23 May 2023 14:54:12 +0200 Subject: 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(+) (limited to 'gcc') diff --git a/gcc/config/avr/avr.cc b/gcc/config/avr/avr.cc index 3170696..a90cade 100644 --- a/gcc/config/avr/avr.cc +++ b/gcc/config/avr/avr.cc @@ -1018,6 +1018,19 @@ 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. */ @@ -14770,6 +14783,9 @@ 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; -- cgit v1.1
