Subject: RE: [PATCH v3] aarch64: rewrite fenv routines in C using
inline asm
+static inline uint32_t read_fpcr_u32(void) {
+ uint64_t x;
+ __asm__ volatile ("mrs %0, fpcr" : "=r"(x));
+ return (uint32_t)x;
+}
+
+static inline void write_fpcr_u32(uint32_t v) {
+ uint64_t x = v;
+ __asm__ volatile ("msr fpcr, %0" :: "r"(x) : "memory"); }
+
+static inline uint32_t read_fpsr_u32(void) {
+ uint64_t x;
+ __asm__ volatile ("mrs %0, fpsr" : "=r"(x));
+ return (uint32_t)x;
+}
+
+static inline void write_fpsr_u32(uint32_t v) {
+ uint64_t x = v;
+ __asm__ volatile ("msr fpsr, %0" :: "r"(x) : "memory"); }
+
Shouldn't the ending brace be on its own line for write_fpcr_u32 and write_fpsr_u32?
