From 3dbaad0a1f27b96462541e1189efe37ffa913e9a Mon Sep 17 00:00:00 2001 From: Albert Ou Date: Tue, 13 Dec 2016 15:05:19 -0800 Subject: Refactor libc stubs into libwrap The --wrap feature of GNU ld supports a cleaner framework for linking in alternative implementations of libc functions without cpp hacks. Place wrappers in separate object files to reduce static code size. --- software/demo_gpio/.gitignore | 1 + software/demo_gpio/Makefile | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) create mode 100644 software/demo_gpio/.gitignore (limited to 'software/demo_gpio') diff --git a/software/demo_gpio/.gitignore b/software/demo_gpio/.gitignore new file mode 100644 index 0000000..35566c7 --- /dev/null +++ b/software/demo_gpio/.gitignore @@ -0,0 +1 @@ +demo_gpio diff --git a/software/demo_gpio/Makefile b/software/demo_gpio/Makefile index 0a0b148..04a11b7 100644 --- a/software/demo_gpio/Makefile +++ b/software/demo_gpio/Makefile @@ -1,7 +1,7 @@ TARGET = demo_gpio C_SRCS += demo_gpio.c C_SRCS += plic_driver.c -CFLAGS += -fno-builtin-printf -DUSE_PLIC -DUSE_M_TIME +CFLAGS += -O2 -fno-builtin-printf -DUSE_PLIC -DUSE_M_TIME BSP_BASE = ../../bsp include $(BSP_BASE)/env/common.mk -- cgit v1.2.3
