how to define single bit in MCU 8051 ide?

[shadababe04]

how can i define single bit in MCU8051 IDE...?
As i define single bit in Keil just like sbit rs=P1^1; IS not working in MCU 8051 IDE?

Have you ever resolved this issue?

Are you still using MCU8051IDE?

A MCU8051 IDE user who's seriously interested to answer the question would review the SDCC manual. http://sdcc.sourceforge.net/doc/sdccman.pdf

From stm32f10x_gpio.h SPL library
set bit 1: value |= GPIO_Pin_1;
clear bit 1: value &= ~GPIO_Pin_1;
invert bit 1: value ^= GPIO_Pin_1;

SDCC has dedicated syntax for bit-addressable SFR, similar to Keil sbit. I don't believe that the ST32 syntax will be understood by the compiler.

I believe the post is off-topic here as it doesn't refer to 8051. 8051 has no 32 bit wide SFRs. Please clarify the subject.
