From 9aade4a816455b758d6211bc7ce2dd931c1598d8 Mon Sep 17 00:00:00 2001 From: Maciej Bocianski Date: Wed, 4 Dec 2019 09:42:44 +0100 Subject: [PATCH] NUMAKER_IOT_M263A: keep __vector_handlers symbol in LTO builds Add a "used" attribute to __vector_handlers to fix ARMC6 build with the "-flto" flag. (Error: L6236E: No section matches selector - no section to be FIRST/LAST. ) This attribute, attached to a function/variable, means that code must be emitted for the function even if it appears that the function is not referenced. --- targets/TARGET_NUVOTON/TARGET_M261/device/startup_M261.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/targets/TARGET_NUVOTON/TARGET_M261/device/startup_M261.c b/targets/TARGET_NUVOTON/TARGET_M261/device/startup_M261.c index 9af13c61ac..58a328e60d 100644 --- a/targets/TARGET_NUVOTON/TARGET_M261/device/startup_M261.c +++ b/targets/TARGET_NUVOTON/TARGET_M261/device/startup_M261.c @@ -193,7 +193,7 @@ WEAK_ALIAS_FUNC(TRNG_IRQHandler, Default_Handler) // 101: /* Vector table */ #if defined(__CC_ARM) || (defined(__ARMCC_VERSION) && (__ARMCC_VERSION >= 6010050)) -__attribute__ ((section("RESET"))) +__attribute__ ((section("RESET"), used)) const uint32_t __vector_handlers[] = { #elif defined(__ICCARM__) extern uint32_t CSTACK$$Limit;
