GCC optimalizace, zahada

[Jaroslav Buchta]

Koukam, casto, ale z tohodle nic moc relevantniho nevykoukam.  Proste je 
BSRR 32b stejne jako BRR kde je vyuzita jen spodni pulka.
polozka struktury je volatile a uint32_t, cekal jsem, ze s tim nebudou 
problemy.

typedef struct
{
   __IO uint32_t MODER;        /*!< GPIO port mode 
register,               Address offset: 0x00      */
   __IO uint32_t OTYPER;       /*!< GPIO port output type 
register,        Address offset: 0x04      */
   __IO uint32_t OSPEEDR;      /*!< GPIO port output speed 
register,       Address offset: 0x08      */
   __IO uint32_t PUPDR;        /*!< GPIO port pull-up/pull-down 
register,  Address offset: 0x0C      */
   __IO uint32_t IDR;          /*!< GPIO port input data 
register,         Address offset: 0x10      */
   __IO uint32_t ODR;          /*!< GPIO port output data 
register,        Address offset: 0x14      */
   __IO uint32_t BSRR;         /*!< GPIO port bit set/reset 
register,      Address offset: 0x1A */
   __IO uint32_t LCKR;         /*!< GPIO port configuration lock 
register, Address offset: 0x1C      */
   __IO uint32_t AFR[2];       /*!< GPIO alternate function 
registers,     Address offset: 0x20-0x24 */
   __IO uint32_t BRR;          /*!< GPIO bit reset 
register,               Address offset: 0x28 */
}GPIO_TypeDef;
