Hardware float option

[parsec67]

Wondering about “Floating-point ABI” setting in VS project Configuration properties->ARM settings, does it have any purpose? I have hardware float set  in my VisualGDB project properties page and the stm32.xml file seems to reflect that the correct library is used, see below. Changing Floating-point ABI has no effect?

<KeyValue>
        <Key>com.sysprogs.bspoptions.arm.floatmode</Key>
        <Value>-mfloat-abi=hard</Value>
</KeyValue>

Hi,

The value in the VisualGDB Project Properties is set for all configurations and is stored in stm32.props:

    <ItemDefinitionGroup>
        <ToolchainSettingsContainer>
            <ARMCPU>cortex-m4</ARMCPU>
            <InstructionSet>THUMB</InstructionSet>
            <FloatABI>soft</FloatABI>
        </ToolchainSettingsContainer>
    </ItemDefinitionGroup>

The corresponding VS property could override it for each configuration, but we do not recommend changing it manually to avoid confusion.
